DON LEMON, CNN ANCHOR: Welcome back, everyone.

It almost began a year's worth of research and an open mind. Now, Dr. Sanjay Gupta says we been misled about medical marijuana and he's changed his mind on the benefits. He'll present his research and reasoning tonight in a new CNN documentary tonight. Sanjay will join me at the bottom of the hour here on CNN.

(MUSIC)

LEMON: Hello, everyone. Don Lemon here in New York. It is at the top of the hour. You are in the CNN NEWSROOM.

We have bizarre, new details about Hannah Anderson. The couple who spotted Anderson and her suspected captor in Idaho say the teen was wearing pajamas. They say she and DiMaggio hiking with a cat and their camping gear looked brand new.

(BEGIN VIDEO CLIP)

MARK JOHN, SPOTTED HANNAH ANDERSON IN IDAHO: These people did not want to talk to us whatsoever. And I said to the girl that was soaking her feet, I said what are you doing with your feet in the water? Don't you know there's fish in there? Kind of joking.

Then, as we turned right away, she didn't -- she didn't make any comment. So, we turned to go away and says, "It looks like we're all in trouble now." All of their gear looked like it was brand new. That was another little flag that wasn't -- just wasn't normal or natural.

(END VIDEO CLIP)

LEMON: You're going to hear much more from these trail riders throughout the hour here on CNN.

In the meantime, Hannah Anderson is expected to rejoin her father Brett today for the first time since a once-trusted family friend shattered their lives. Hannah was rescued from the Idaho wilderness yesterday after the FBI shot and killed her alleged captor James DiMaggio. Also suspected of murdering Hannah's little brother and her mother.

FBI search and rescue teams hiked for hours to find her. Some rescuers wept once the mission ended successfully.

Physically, Hannah's OK. But the trauma of her ordeal could linger for years. And for Hannah and her family and her father, this family reunion may be filled with joy and grief. They each have each other, but they have lost so much.

It was an agonizing week for the entire family of 16-year-old Hannah Anderson, waiting, hoping, praying for good news and the reunion sure to be bittersweet. Remember Hannah's mother and brother died a week ago. Their remains found in the suspect's burned out house near San Diego.

CNN's Paul Vercammen is live in San Diego right now.

And you just spoke with Hannah's grandparents. What did they tell you, Paul?

PAUL VERCAMMEN, CNN CORRESPONDENT: Well, Sara and Ralph Britt first wanted to reach out to the horseback riders and thank them profusely for helping to rescue their granddaughter. This was for them the best case scenario that Hannah survived. And they made an illusion to Mr. DiMaggio's death and saying, well, I guess there won't be some sort of trial and maybe that's good. They also said that those horseback riders are awesome.

And then, Don, we talked about other things. Of course now, this is the gut wrenching part. They have to plan for a memorial service for their only child, their daughter Tina, and for their grandson Ethan.

And I asked them was there anything that suggested to you that there was something untoward or odd going on with Jim DiMaggio? Any indication that he might snap? Here's what they had to say.

(BEGIN VIDEO CLIP)

SARA BRITT, HANNA ANDERSON'S GRANDMOTHER: What surfaced at the end here was that, you know, just a few weeks ago Hannah made a comment to her friends that she felt awkward, weird around him because he said he had a crush on her. And she was afraid to tell her parents because Jim's family and her friends, you know, the awareness wasn't there for them to tell their parents or another adult so that, you know, we could have acted on this earlier, a week earlier. And it might have helped.

(END VIDEO CLIP)

VERCAMMEN: And Sara Britt also saying this is a cautionary tale and for all teens and parents and grandparents to pay close attention. Just see if there are any signs out there that someone might be grooming a child or plotting something, anything out of the ordinary, Don.

LEMON: Let's talk a little bit more about grooming, and possibly in this particular situation. There's lots of questions about whether Hannah was kidnapped or willingly went to DiMaggio. Given the details that we just heard, the people who spotted them said. Have police given you any more information about this?

VERCAMMEN: Yes. On camera yesterday talking to a captain with the San Diego County sheriff's office, he flatly said they always considered this to be a straight-up kidnapping. That Hannah was taken against her will. And then he sort of characterized this off-camera saying she went into survival mode in his estimation and that survival mode was go along with DiMaggio and don't do anything so radical as to cause him to snap further and perhaps kill her.

So, they consider this to be a kidnapping. No debate at the sheriff's office. And also among Hannah's relatives, they say there's no way she would have gone with this DiMaggio willingly -- the once-trusted family friend who basically turned his back on all of them and shattered this family.

LEMON: Paul Vercammen, San Diego, California. Paul, thank you very much.

One missing person case ends with Hannah Anderson's safe recovery. But there is another one today. An active Amber Alert in Rhode Island. This one for a little boy just two years old.

Nick Valencia following this one since this morning for us.

Nick, who is this boy? And what do police think happened to him?

NICK VALENCIA, CNN CORRESPONDENT: Hey, Don. This 2-year-old boy is Isaiah Perez. And what police tell me is that this boy was in a house where two people were found dead and that he was allegedly abducted from this house in Johnston, Rhode Island.

Now, I spoke to a source -- a local law enforcement source in Rhode Island and they said a suspect in connection with this case was arrested this afternoon in Fall River, Massachusetts. That's about 30 or 45 minutes outside of Johnston, Rhode Island.

It is worth noting, though, Don, that there are conflicting reports. "The Boston Globe" is saying that that arrest was a false alarm. They cited a Massachusetts state police department source in that. We doubled back with our sources and they say no a suspect is definitely in custody.

But the bottom line here, don, is that a 2-year-old boy is still missing and that this Amber Alert is still very active.

LEMON: What is the relationship between this missing boy and Malcolm Crowell?

VALENCIA: That's what we're trying to figure out and trying to establish right now. We know that there's some type of a relationship between Crowell and the two victims in the house and this little boy. We just don't know what that relationship is. And police investigators in Johnston are holding their cards close to the chest on this one. They didn't release any more information on this besides saying this man you're looking at here is a suspect in connection with this case with the Amber Alert.

Isaiah Perez, two years old, we're trying to get a picture of him as well. Right now we only have a photo of the suspect in this case. That 2-year-old little boy is still missing -- Don.

LEMON: All right. Thank you, Nick Valencia, on top of this story for us in Atlanta.

VALENCIA: You bet.

LEMON: Search and cleanup efforts are pressing ahead in Colorado following incredible flooding. Homes were damaged and properties destroyed from torrential rain Friday in Manitou Springs, a community just west of Colorado Springs.

You may have seen these incredible pictures. Rain turned this highway into a raging muddy river on Friday. Cars and people inside of those cars. One person was found dead. Two others are still unaccounted for.

In California now, firefighters have turned the corner in their battle against the Silver Fire burning in the mountains east of Los Angeles. The 19,000-acre blaze is 75 percent contained. But in four days, it's done a lot of damage. Flames destroyed more than two dozen homes and injured 10 firefighters.

The trail riders who spotted missing Hannah Anderson and even talk to her and her kidnapper are giving some amazing details about their encounter. Much more from them throughout the hour here on CNN.

But, first, the president lays out a new plan when it comes to how the government watches you. Good plan? We're discussing, next.

(COMMERCIAL BREAK)

LEMON: All those American embassies that shut down overseas last weekend are open again today, all but one. This one, the U.S. embassy in the capital of Yemen. It will remain closed until the State Department decides the threat of an attack there is lower.

A total of 19 U.S. embassies and consulates across the Middle East and Africa closed last Sunday when some intercepted communications hinted that al Qaeda was going operational with a strike plan.

Here in the U.S., the Osprey aircraft that's carried troops and out of battle areas overseas is joining President Obama's travel detail. The president's security staff arrived at Martha's Vineyard this weekend aboard the Osprey. The sleek tilt rotor aircraft takes off like a helicopter and flies like an airplane.

The Osprey had a checkered past with many crashes during initial development and training. It has been redesigned for safety. And right now, the plan is for the president's travel detail not President Obama himself to fly on this aircraft.

You know, it may be a quiet week on the Hill, but President Obama was far from silent about a slew of topics during a news conference Friday. Although his assertion that Edward Snowden was not a patriot for leaking details about top secret U.S. surveillance programs was brushed aside today by Snowden's father.

Listen.

(BEGIN VIDEO CLIP)

LON SNOWDEN, FATHER OF EDWARD SNOWDEN: In terms of him characterizing my son as a patriot or others like Peter King who characterizes him as a traitor, what I would say is that my son has spoken the truth. He has sacrificed more than either the president of the United States or Peter King have ever in their political careers and their American lives. So how they choose to characterize him really doesn't carry weight with me.

(END VIDEO CLIP)

LEMON: So, joining me now to break it down, CNN commentator L.Z. Granderson. And then a little bit later on, the anchor for TheBlaze.com, Amy Holmes, will join us.

So, you know, ahead of the question and answer session on Friday, L.Z., the president unveiled new measures to instill transparency in government surveillance. How does he sell this in the wake of Edward Snowden?

L.Z. GRANDERSON, CNN COMMENTATOR: I don't really think he can. This is a PR nightmare for the Obama administration right now. And all the things he's talking about, all the things he's shared sounds like a lot of talk to the American people.

You know, it's really disappointing in a sense that for the most part, the things we discover from Snowden are things that we already knew and just forgotten. They have been re-characterized and reframed. So, now, it looks as if it's breaking news and Obama is putting out a lot of fires.

And at this point, with the economy still being sluggish and people having a huge distrust of the government, on the heels of the IRS scandal, and now this, I don't really think there's really very much he can say to the American people other than totally getting rid of the NSA that's going to win over Americans' trust, most Americans' trust at this point.

LEMON: Are you saying now because you're saying there are details coming out that had already been out before? You know, what the president said --

GRANDERSON: Right.

LEMON: The president said that -- I think it was last week or the week before, where he said -- we've been involved and we've been, you know, sort of deluded with all of these false scandals, or fake scandals that don't really amount to anything. Do you agree with the president that this is a false scandal, the NSA program scandal?

GRANDERSON: This -- I agree in a sense that the way it's been characterized is that this is something that the Obama administration sort of created. This is something that we've been doing not too much further beyond September 11th.

It's been reported by the media. It's been in newspapers for a decade. And so, in fact, I was watching "Real Time with Bill Maher" and he read a story from "USA Today", I think that was back from 2006. And it sounded exactly like a story that was being read in 2013.

And so, no, a lot of the things we were talking about was not new. Because it's been re-characterized and because it comes on the heels of the IRS, it comes on the heels of Benghazi, it's a not a fake scandal per se, but it's a re-characterization of old news, if you will.

LEMON: OK. All right. Amy, I'll let you weigh in on that, but also whether or not this is old news.

But I want to talk to you about this. The House Homeland Security Committee Chairman Mike McCaul said today he doesn't believe President Obama would have acted to reform a National Security Agency program or programs were it not for the leaks from Edward Snowden. Listen and then we'll talk.

(BEGIN VIDEO CLIP)

REP. MIKE MCCAUL (R), TEXAS: I think when the story initially broke, the president went under recovery. He finally came out last Friday trying to come up with ways to salvage the program by window dressing, you know, forming a Web site, for instance, an outside group.

And the problem fundamentally is he's failed to explain these programs which are lawful, which have saved lives, which have stopped terrorist plots. He has not adequately explained them or defended them. And now, he's in a bit of a mess and I'll tell you why, because on the heels of the IRS scandal where people don't trust this government, this administration with their tax records, they sure don't trust this administration with their phone records. I think that's the dilemma the president's in right now.

(END VIDEO CLIP)

LEMON: All right. To Amy Holmes right now -- do you think reforms will ease public concern or continue to stir the pot?

AMY HOLMES, ANCHOR, THE BLAZE.COM: Well, I think it's a good step in the right direction, but it's still fairly cosmetic. Yes, we now will have someone who's out on the half of civil liberties. But it's still going to be a secret court and these are going to be secret renderings, the decisions, that we won't understand exactly how the FISA court arrived at its conclusions, whether it's yea or nay, to perform surveillance on whatever target. But I think that the congressman there is exactly right. The president would not have acted if not for Snowden and all of these leaks. And let's remember that his own James Clapper, the director of national intelligence, when he was in a Senate hearing being asked directly about this program as he put it, he gave the least untruthful answer that he could.

So, in other words, we have the administration lying to sitting Democrats -- sitting senators, rather, including the Democrats, who is the chair of that committee, and not providing, you know, accurate information about what the government's doing. I would also throw into the mix that I think the surveillance of James Rosen, and the FOX News reporter, and that secret court document signed by our attorney general, that lit the fire under the media for the first time. And that they are holding this president more accountable than they did up until this point.

LEMON: I was going to move on and go to a different subject, but since we got you late -- we had a bit of technical issue -- I think this is a good subject to stay on, because this is one of the most important things in the news this week.

L.Z., you sort of -- as she was talking, shaking your head. You disagree with what she's saying?

GRANDERSON: No. No. I wasn't disagreeing. I was actually agreeing with what she was saying. I mean, this is a bit of a -- as I said earlier, this is a pr nightmare. And the people are listening to what the president says. But people just don't trust the government. They didn't trust the government before President Obama. They don't trust the government now.

And I'm not sure if we had anyone in the pipeline for 2016 that could restore that trust any time soon. It's something that --

LEMON: L.Z., quickly here I want to ask you when people say, how's this for the most transparent administration? First to L.Z. and then to Amy.

GRANDERSON: Well, you know, you have to compare that transparency to other administrations. I think people misinterpreted what he said as meaning he's going to tell you everything. By saying the most transparent, he means in terms of -- in comparison to other administrations. And I still find him to be a lot more transparent than some of the dealings we've had with previous presidents.

But he's not -- he didn't stand up to say he's going to be completely open with everything and he has not been completely open with everything.

LEMON: OK. Amy, quickly, if you will?

HOLMES: Well, clearly, we do have to have national security secrets. The president can't be revealing top classified information. Even though he does when it's in the administration's to their own benefit. For example, the 19 embassies that were just closed, we learned leaks that that was possibly because of some conference call between Ayman al-Zawahiri and 20 other al Qaeda affiliates and operatives. I think that's a leak that harmed national security.

But in terms of transparency, we're not -- we see stonewalling from this administration over and over. And, in fact, Attorney General Eric Holder has been held in content for his stonewalling on Fast and Furious. We still haven't had officials come clean about the IRS scandal -- still trying to get to the bottom of that.

LEMON: OK.

HOLMES: It's just one thing after the next where this administration, I think, is just trying to play rope-a-dope so that they get past these scandals. But as we now know, the president's approvals are now, it looks like at all time lows. Gallup has him at only 42 percent approve.

So, all of this is taking a toll on the president's credibility.

GRANDERSON: But still --

LEMON: We've got to run because of the breaking news. Thanks to both of you. Thanks to L.Z. and Amy as well.

No Tiger/Phil at the top of the leader board. But an exciting finish is shaping up at the PGA championship. We're going to take a look live at the course, next.

(COMMERCIAL BREAK)

LEMON: To golf now. It's the last major of the year, the last one.

Joining me now is CNN Sports' Rachel Nichols.

Rachel, it's not Tiger or Phil, but I don't know. What a day for Jason Dufner, right?

RACHEL NICHOLS, CNN SPORTS: Absolutely. He is still leading by two with two holes to play. And he looks a little nervous a few holes ago. You can certainly understand why.

Two years ago, he was set to win this major. He was leading by five strokes with three holes to play which, look, is basically as much of a lock as you can get without actually winning the thing. The problem is, he completely self-destructed and didn't actually win the thing.

So, now, he is trying to atone for that. Really the big question is, what pose is he going to strike if he does get the trophy?

He's what we call a laid back kind of cat. In fact, why don't you take a look at this picture? This is when he was visiting a school in Texas earlier this year doing a good deed. But looks, well, let's just say, comatose sitting there.

And his fellow golfers were so amused by this, they started calling it Dufnering, sitting there the way Jason Dufner did. They put up their own photos on Twitter and Facebook imitating Jason Dufner doing this.

And they are all rooting for him to Dufner with the trophy today. I know, Don, you've been working on your Dufnering since we talked about this yesterday. We got to cross our fingers and hope that if Jason Dufner win, he does a little extra Dufnering today.

LEMON: Once I'm on a full shot, I'll Dufner it for you. Maybe I'll send you a picture.

Well, let's move on from Dufner and let's talk about Tiger --

NICHOLS: All right. I need that.

LEMON: All right. Did he struggle again today because he was like 44th I think yesterday or something?

NICHOLS: Yes. He was at even par. It's frustrating for him because not only has he not won in the past five years a Major, this time he wasn't even close. There were a couple Majors where he felt he was in contention, had something to play for Sunday. But this time, he said it was so frustrating because he didn't have anything to do this weekend.

He is now going to be 38 years old this December, Don, and I've got to tell you, there are certainly golfers who have won past that age. Phil Mickelson just won the British Open this year at 43. But Tiger just doesn't want to win one more Major. He wants to win five more Majors to surpass Jack Nickelson's record. That's only going to get tougher as he gets older.

LEMON: Such an old man at 38.

All right. Thank you, Rachel. Appreciate that.

Our top story now. A kidnapped California teen rescued from the Idaho forest, thanks to these folks horseback riders who ran into Hannah Anderson and her kidnapper. Their compeling details for their encounter next.

But first this, when President George W. Bush underwent a procedure this week to clear a blocked artery, it was a health wake up call heard by millions. Here's Tom Foreman with this week's "American Journey."

(BEGIN VIDEOTAPE)

TOM FOREMAN, CNN CORRESPONDENT (voice-over): In office and out, George W. Bush has been regarded by many as the most fit president ever -- mountain biking, running, swimming, golfing, weight-lifting and laboring on his ranch. His annual physicals while in office found him in excellent health with no history of hypertension or diabetes and low to very low coronary artery disease risk.

So when physicians found a heart blockage and inserted a stent to re- open an artery, some people may have been stunned but not Dr. Barron Lerner. DR. BARRON LERNER, PROFESSOR, NYU SCHOOL OF MEDICINE: I think it is an instructive case that people should go to their doctors and not assume for example that just because they exercise a lot, they don't necessarily have a heart problem.

Lerner wrote a book on the impact of celebrity health issues called "When Illness Goes Public". And he says when famous people face illness this is the good that almost always follows. Public awareness and action rise sharply.

When former First Lady Betty Ford for example disclosed she had breast cancer, the number of women seeking screenings rose.

When Katie Couric's husband died of colon cancer, screenings for that disease increased too.

LERNER: I think the best thing that comes out of this is that somebody reads about this and then they pursue it more.

FOREMAN (on camera): Over the past half century or so, each president has maintained some sort of physical fitness during and after his term.

(voice over): Nixon bowled, Ford golfed, Carter jogged, Reagan rode horses, Clinton ran too, Obama plays basketball and the first President Bush even jumped out of an airplane. Each one a living reminder of how much watching your health matters whether you're famous or not.

Tom Foreman, CNN, Washington.

(END VIDEOTAPE)

(COMMERCIAL BREAK)

LEMON: Trail riders spotted 16-year-old Hannah Anderson and her alleged captor in the Idaho wilderness and red flags went up. Their camping equipment was new, they were hiking with a cat in the woods, and Anderson looked scared.

(BEGIN VIDEO CLIP)

MARK JOHN, SPOTTED 16-YEAR-OLD WITH ALLEGED CAPTOR: When we got up on the mountain that morning, we hadn't been into the lake fishing for quite a while. And so that Tuesday morning we took off and went up to the lake and that Wednesday morning we rode in. We set up camp, rode in. Mike here was first one to encounter the two hikers. The guy and the girl. The red flags kind of went up on him.

UNIDENTIFIED REPORTER: What red flags?

JOHN: The -- the girl, she had -- I'll let Mike explain that to you, what he saw. And then when we went to the lake then they showed up at the lake and they was like a square peg going into a round hole. It didn't fit. He might have been outdoors man in California, but he was not an outdoorsman in Idaho. He didn't fit. And so when we got back to the camp that night after fishing and double twice we encountered them. Then we discussed it. And then we got home Thursday evening and I put all the horses away, took care of our livestock and everything. Then we went into the house and the news flashed on. And the AMBER alert was on the television. And I told my wife, I said that is that girl we seen on the mountain.

But there was no phone number. So I talked -- my wife and I called back and we said look at the TV and see if that girl doesn't look exactly like what we seen on the mountain. They kind of confirmed that. And then I called a friend of mine in the Idaho State Police, Tom Nesbitt (ph). He used to work for me as my investigator when I was a sheriff.

And so I had all the confidence in the world in him. And I called him and I told him what we'd seen and what was going on. And I knew that he'd get the ball rolling and keep it rolling. And then the next morning we heard on the news where they found the car exactly where we told them it would be.

UNIDENTIFIED REPORTER: You guys see the car, too?

UNIDENTIFIED FEMALE: No.

JOHN: We never seen the car. Our trail had -- our trail going in teed, came to a T with the trail that they come in on.

UNIDENTIFIED REPORTER: What was the camaraderie like between the two? Did she feel frightened --

JOHN: I can't hear you.

UNIDENTIFIED REPORTER: What was the feeling between the two? Did she seemed frightened up there at all?

JOHN: They didn't -- they didn't -- they weren't friendly. They didn't talk.

UNIDENTIFIED REPORTER: Didn't talk at all?

JOHN: They answered some of Mike's questions.

UNIDENTIFIED REPORTER: What did they say?

JOHN: Mike?

MIKE YOUNG, SPOTTED HANNAH ANDERSON IN IDAHO: I just asked him where he was headed. And he said he was going to the Salmon River hopefully. And -- but they were headed the wrong direction to get to the Salmon River. That was one red flag for me.

UNIDENTIFIED REPORTER: How would you describe how Hannah was behaving?

YOUNG: She was trying to turn her face away. I talked to her -- well, I didn't talk to her. I was mainly concentrating on him, but she was kind of had a scared look on her face when I first come up the trail. We didn't know if it was from the horses or what. But then when I turned and talked to him a little bit, I just did -- just had a gut feeling about him.

UNIDENTIFIED REPORTER: How long was that interaction?

YOUNG: Just a few seconds. And then -- and then when we went up the trail a little ways, I turned and told them these guys that there was something wrong there. It just wasn't right.

(END VIDEO CLIP)

LEMON: You're going to hear more from the riders who spotted 16-year- old Hannah Anderson with her alleged captor coming up on CNN.

We have brand new photos of the suspect James DiMaggio's car camouflaged in the woods. Look at these photos. Piles of sticks on the car. Hidden in the woods to avoid being spotted. Here's what DiMaggio's vehicle actually looked like. His purple car would have really stood out.

But next, hot weather that may be making you cranky. There might be some science behind that.

(COMMERCIAL BREAK)

LEMON: We are launching a new segment here on the weekends called "The Science Behind" where we hope to teach you the why behind the what.

Ever wonder if the weather affects our behavior? CNN's Jennifer Delgado explores the science behind climate change and an increase in violence.

(BEGIN VIDEOTAPE)

JENNIFER DELGADO, AMS METEOROLOGIST (voice-over): Whether it's politicians behaving badly or civil unrest halfway around the world --

REZA SAYAH, CNN INTERNATIONAL CORRESPONDENT: We're getting reports from state media that anywhere from 10 to 23 people were killed.

DELGADO: -- it's clear that violence has no borders. But now scientists from the University of California-Berkeley have determined that the world could turn into an even more violent place. With murders, assaults, and even wars to rise if extreme weather occurs with greater frequency.

SOLOMON HSIANG, ASSISTANT PROFESSOR, UNIVERSITY OF CALIFORNIA- BERKELEY: We think that our evidence suggests that conflict could be a critical and important impact of climate change on future societies and that we want to take it seriously and consider what the world will look like in the future and whether or not our actions today can actually be effecting the safety of people.

DELGADO: Floods, heat waves, or droughts can spur conflict. And Hsiang says violence can sharply increase.

HSIANG: When we think about anthropogenic climate change, climate change in the future, what we have done is we've calibrated our results to what we expect to observe with about two degrees warming by 2050 we would observe roughly somewhere around 8 to 15 percent more interpersonal violence in most locations around the world and roughly 30 to 50 percent more inter-group conflict.

DELGADO: Researchers also looked at how ancient civilizations may have been impacted by climate change by studying layers of mud in the ocean and lakes or taking information from old trees. Establishing a link between past climates and the collapse of major civilizations like the Mayan empire.

HSIANG: We were surprised by the strength of our results in that we were able to observe these types of relationships around the world across different populations and throughout human history.

(END VIDEOTAPE)

LEMON: All right. That was Jennifer Delgado reporting.

One of the hottest teams in baseball is the Atlanta Braves. And one of the players leading the charge for them hasn't exactly taken the path of least resistance to the majors. We're hearing from him next.

(COMMERCIAL BREAK)

LEMON: Well, the PGA championship down to the wire but the player a lot of people are talking about isn't even on the leader board.

Terence Moore is in Atlanta. He's a columnist for MLB.com and a sports contributor to CNN.com.

Before we get to this, are you jealous of this beautiful weather here in New York?

TERENCE MOORE, CNN.COM SPORTS CONTRIBUTOR: Listen. We've been in a rainstorm here in Atlanta forever. That is fabulous. Come back and join us in the wet and the rain. But it's been hot. It's been hot.

LEMON: So that's good for Atlanta baseball. But we're going to talk about that. But CNN's Rachel Nichols spoke just a few minutes ago. Tiger hasn't won one of golf's major tournaments in five and a half years. Will he ever win another one?

MOORE: Well, in the long run, yes. You know, he's only 37. And remember Jack Nicklaus won his last major at 46. But in the short run, I'll tell you, Don, I think this guy might need to invest in a sports shrink. OK? There is no way you go from looking invincible to the week before as he did in Akron shooting a 61 at some point to looking like he did this weekend looking totally clueless. It's got to be totally mental.

And I just wonder, does Dr. Phil handle golf cases? You know that or not? I don't know. LEMON: Yes. I don't know. Maybe he needs a little some hypnosis.

MOORE: He needs something.

LEMON: Some therapy.

MOORE: Particularly when it comes to putting.

LEMON: Yes. We won't go there.

(LAUGHTER)

Let's talk baseball. The Atlanta Braves had been on fire of 14-game winning streak. That ended just last night and they've already won today. But they've had lots of injuries. And as you wrote in your column this week, they had 12 players under the age of 25.

MOORE: Yes.

LEMON: How are they doing?

MOORE: Well, it's all about resiliency. This is the most resilient team in Major League baseball. And I'll tell you, like you said, we saw it again this week. And the fact they lost, they had that 14-game winning streak snapped, came back today, blasted the Marlins. Then you're talking about a team with a slew of injuries. Lost their entire starting outfield at some point in the season. Was able to overcome that.

But besides resiliency, Don, they've also got great pitching. They also have a manager in Freddie Gonzalez who's brilliant at dealing with young players. And also he makes these unorthodox decisions that don't blow up in his face. At least not yet.

LEMON: Yes. OK. One of their amazing players, 26-year-old rookie named Evan Gattis. He once quit the game.

MOORE: Yes.

LEMON: He worked odd jobs. He lived in his van. He struggled with depression. And now he's a key player in the Braves' march to post- season. You spoke with him not long ago at Turner Field and you asked him about some quirky habits he has like not wearing batting gloves. Here's what he told you and then we'll talk about it.

EVAN GATTIS, ATLANTA BRAVES CATCHER: No batting gloves. My mom says that's because I would have lost them. But I never liked batting gloves. I never like -- I always like to feel the bat. And one of my managers coming up in the minors put me into pinch hit. The only time I ever pinch hit before he said you didn't take practice swings. You know, I put you in that game. He was yelling at me and stuff. I don't know what that's all about. I pride myself on being ready to hit.

(END VIDEO CLIP)

LEMON: I like it when people overcome adversity. Evan Gattis, is he the real deal?

MOORE: You know what, he had three hits again today. And you don't go from being homeless to spending your rookie year in Major League Baseball hitting 15 homeruns as a third string catcher and be a fluke. So to answer your question, yes.

LEMON: All right. Thank you, Terence. Appreciate it.

We'll be right back, everyone.

(COMMERCIAL BREAK)

LEMON: Trail riders spotted 16-year-old Hannah Anderson and her alleged captor in the Idaho wilderness and red flags went off. Their camping equipment was new, Anderson looked scared. Take a listen.

(BEGIN VIDEO CLIP)

JOHN: We was already saddled up and mounted our horses and everything. That's when we first seen them. We found -- felt that was quite strange because they had a whale of a hike coming down through that -- the rocks and that steep country. And when I say steep, when we go down some of those switchbacks going down through there on that trail, they just about take the hide off of a horse's tail going down there because they're sliding down on all fours getting down to the lake.

So we was kind of surprised because they had hiked a long ways. And they had some big rucksacks at that time sitting on the ground. Like I said, she was soaked and -- but he was off to the side of the trail petting a gray cat.

UNIDENTIFIED REPORTER: What?

JOHN: Petting a gray cat. And I made a comment then. I said, what are you doing with a cat in here? Them cats are only good for wolf, you know, to chum a Wolf in or to bring in a mountain lion or something. And he just -- he just kind of grin then had a smirk on his face. Again that was strange because in the back country in Idaho you run across somebody back there hiking, they are usually quite friendly and they exchange pleasantries, and they exchange knowledge about where they've been, what they've done, where they were going.

These people did not want to talk to us whatsoever. And I said to the girl, who was soaked in her feet, I said, what are you doing with your feet in the water, I said, don't you know there's fish in there? Kind of joking. And then as we turn to ride away, she didn't -- she didn't make any comment. We turned right away and then she says it looks like we're all in trouble now.

(END VIDEO CLIP)

LEMON: And so the male riders noticed a lot of technical details that set off red flags. The wives noticed an entirely different set of red flags. And I talked to psychologist Wendy Walsh about gender differences and intuition.

(BEGIN VIDEO CLIP)

WENDY WALSH, PSYCHOLOGIST: There were four people on horseback in the outdoors, two of them were trained in intuition, a former sheriff, a former army marksman -- sorry, army ranger and their wives. So, you know, studies show, research shows that the best kind of group intelligence is actually two gendered intelligence because women tend to have social intelligence, men to have maybe more visual intelligence.

So they're looking at kind of his backpack, you know, he's a California guy, what's he doing here, and the women are looking at, what's the relationship? This young girl, what's the deal here? So I think that was very helpful that you had the four people together and you had both genders.

LEMON: Sixteen-year-old Hannah Anderson was rescued without any significant physical injuries. The suspect, James DiMaggio was shot and killed. He allegedly killed Hannah's mother and brother before leaving California with Hannah.

Developments now in the case of a missing little boy. Police in Rhode Island tell CNN they have two men in custody. They are not confirming yet whether one of them is the man, this man right here, Malcolm Crowell. Authorities have been searching for him since this morning when a 2-year-old boy went missing from a house where two people were killed.

We're following this one closely and will update you when we know more about the story.

CNN's Dr. Sanjay Gupta has had a change of heart. A big one. He now supports the use of marijuana as a medication. He explains why live next.

(COMMERCIAL BREAK)

LEMON: CNN documentary airing tonight. It may make you rethink what you thought you knew about pot.

Chief medical correspondent for CNN Dr. Sanjay Gupta spent nearly a year investigating the impact of marijuana on the body. He joins me now.

So, Sanjay, you wrote an op-ed just a few days ago about weed. And you wrote this, "We have been terribly and systematically misled for nearly 70 years in the United States and I apologize for my own role in that."

That's powerful words. How have we been misled? DR. SANJAY GUPTA, CNN CHIEF MEDICAL CORRESPONDENT: Well, you know, I think, you know, as a starting point, if you look at the literature in the United States on medical marijuana there's a lot of papers out there and if you look at them you find that the vast majority of them are basically looking at how to figure out if there's harm or some problem or a peril with medical marijuana.

Very few actually designed to look at benefit. And I looked at these studies over the years myself, Don, and, you know, if you look at it it's a very distorted picture of the use of medical marijuana. The potential of medical marijuana. And I think that that was, you know, part of the systemic misleading and something that I had reported on in terms of my, you know, just not being that impressed with medical marijuana.

It was when I started to dig deeper, look outside the country, look at other labs that were doing some incredible research, and then most of all talked to a lot of patients, legitimate patients who have legitimate problems, I realized there was something more here.

I mean I -- and again, I was quick to dismiss those patients as, you know, these high visibility malingerers who were looking to get high. But --

LEMON: Yes.

GUPTA: I realized there was more.

LEMON: And it's not just that. I mean, sometimes it's the only thing that works, right?

GUPTA: I think so. It can be the only thing that works. We want to know if something is safe. We want to know if it works, and we want to how it works compared to other things.

I met so many patients in the making of this documentary, Don. Let me just show you one example.

(BEGIN VIDEO CLIP)

GUPTA: Meet 19-year-old Chaz Moore. He uses many different strains of marijuana. Many of them high in CBD to treat his rare disorder of the diaphragm.

CHAZ MOORE, PATIENT: My abs will like lock up --

GUPTA: That's why he's talking this way. Almost speaking in hiccups, like he can't catch his breath. He's about to show me how the marijuana works. He's been convulsing now for seven minutes.

How quickly do you expect this to work?

MOORE: Within like the first five minutes. And I'm done, like.

GUPTA: That's it.

MOORE: That's it.

GUPTA: It was actually less than a minute.

(END VIDEO CLIP)

LEMON: OK, so, Sanjay, I want to ask you and a lot of people at home are going to want to know. How do we know he's not faking it?

GUPTA: Well, he had been seen by doctors. He had been in an ICU. He'd been treated with all sorts of different medications. I mean, he had a known diagnosis that he had been trying to get treated for years. I mean, you know, and actually at one point had been on so many different narcotics and muscle relaxants that he -- you know, he was -- he was concerned that he might actually overdose on one of those. And someone suggested marijuana.

And again, Don, a high CBD, low THC. To a lot of people, that's going to sound like alphabet soup, but it's important. THC is the stuff that gets you high. The strains that we're talking about have very, very low, negligible amounts of THC and much higher CBD which is the stuff that's the medicinal. So, you know, think of this as a medicine in that regard.

LEMON: OK. We have less than a minute left here, Sanjay. And I'm also going to be honest because I know some people at home are thinking the same thing, they're like, we've known this for a long time. Why? Actually when many of us heard we're doing a documentary on marijuana, we said why, it's like same-sex marriage. Isn't it over? Like the train has left the station.

GUPTA: Well, I mean look. If you look at the opinions around the country, I think there's definitely been shifts back and forth. But it's still a pretty divisive issue, Don.

LEMON: Right.

GUPTA: I mean, I appreciate what you're saying but I guarantee you, I promise you, there are a lot of people who don't share that point of view.

LEMON: I'm trying to get -- you know, what I'm trying to get from you is why. I think it's amazing that you have changed your opinion and why people should watch. That's what I'm saying.

GUPTA: Yes. No, I mean, look. It's a yearlong investigation into this. I mean, for a lot of people out there who's sort of listen to the anecdotal notes, they listen to the hyperbole or the conjecture, but they really want to be informed on this issue then it's time. I mean, it's time.

LEMON: Yes.

GUPTA: I'm not sure it's going to change people's minds, it may, it may not. That's not the point.

LEMON: I think it will. GUPTA: The point is it should inform.

LEMON: I think it will. I think if someone like you changes their mind I think that's why we should watch this.

Sanjay, we have to run because we want to see your special.

Sanjay's special begins one hour from now. One hour from now. I'm certainly going to watch. I hope you will, too. And meantime Sanjay and I are going to sit back and watch Anthony Bourdain. Here it is right now.
