snowmobile? >> definitely not. we're lucky to get snow once a year. this year we couldn't find snow anywhere. we had to go to upper michigan to get some snow, and there still wasn't any up there. but a lot of the time we'll ride our quads and practice on that, and then we have a way to set up the snowmobiles to ride in texas. i mean, we can make it happen. >> all right, colton moore, i'm glad you're a-okay. protect that head. if not, sanjay gupta is going to find you because we have a big documentary coming up on sunday. colton, thank you so much. now watch this. top of the hour, i'm brooke baldwin t baldwin. the final weekend before the florida republican primary. a final pronouncement on facebook today. a manhunt for the killer of a would-be hero, this good samaritan story out of new orleans and a monster home invader will die for his crimes.

today's reporter roulette. here we go. jojahn, straight to you in miami where newt gingrich is interest to hold a big event there. last night he had a bit of a weaker showing. what is his tacamp saying about that today? >> the first observation i have to make is the candidate looking a little tired here in south florida. a long slug down from jacksonville after the debate. now here? south florida, pu-- now here in florida, pushing for the hispanic vote. he's wishing certain questions had been asked in certain ways. meanwhile, the speaker, as i said, reaching out to the latino voters here in south florida, really making a big play over

h support of his portion of the dream act that will allow military who are immigrants to go on to become american citizens. hoping that plays very well with the immigrant community here in south florida. as we move into the weekend, newt gingrich is planning just a flurry of activity across this state to try to drum up support. because, frankly, brooke, he's in a tough spot. he's in a position where his debate mojo seemed to have failed him just a little bit. he is being beaten in the air out here in television ads and he doesn't have a great organizing on the ground, at least compared to mitt romney. so a tough slog right now in south florida for newt gingrich, brooke. >> you mentioned hispanic vote. one in ten voters in south florida are hispanic. jojahn, thank you. apparently the social media site ready for a big move. what is it?

>> yeah, it's possible. i mean, it's still just being talked about, but facebook could actually file the paperwork to go public as soon as next week. this is coming from the wall street journal and says the exact timing is still being discussed, so we don't really know, but an ip filing filed sometime this year widely expected. this is going to be one of the biggest ipos this year, obviously. facebook looking to raise $10 billion by selling just a fraction of the company to the public. that could benefit the company about $100 billion. when it does file the paperwork, we might learn things like what the ticker symbol might be, whether it's on the nasdaq or the new york stock exchange, and possibly a little bit about what facebook makes. this is just talk, it hasn't been confirmed. it's heating up, and if we see it next week, it will be very exciting. >> there's been a lot of talk about it, but that's the first time we've heard potentially a

time frame. felicia taylor, thank you so much. david mattingly here on the hunt for a killer. horrible story, these two little boys saw the whole thing happened. at least the woman apparently being carjacked is okay. but the fbi is involved. why? >> a carjacking is a federal crime, but that's not exactly why the fbi is involved here. new orleans has a terrible violent crime problem right now. mike ainsworth's murder was 25 days? january and that was already wednesday. there's been another murder since then. the city is having a real big problem. the fbi has been working with the entire city on their violence problem. this time the fbi has been going door to door with homicide detectives trying to get information on this particular murder just because of the way it happened. this man was trying to be a hero, trying to help one of his neighbors in distress and ended up paying the ultimate price right there in front of his children.

>> we told the story yesterday and threw up a sketch. do they have any leads on the suspect? >> the police chief was talking to a crowd of concerned residents last night. he says, yes, they do have leads, they're following up on them. he said he felt good about the way the investigation was going. they have a composite of the suspect. we can show that to you right now. he's described in his 20s, between 5'5" and 5'8". there is a reward and this is getting to be the worst time for the city of new orleans with mardi gras just a few weeks away. a man convicted of invading a family's home, killing the mother and two young daughters, tells the court he has to learn to forgive himself. a federal court says, may god have mercy on your soul and sentences him to death. next reporter brian.

what did he say about the murders of jennifer petit and her two daughters? >> reporter: that's right, brooke, he stood up in a prison orange jumpsuit and shackles and he read from about an eight-minute prepared statement. in it he said, i did not want those innocent women to die. he went on to say, i don't need 12 people to tell me what my motivation was. i did not rape, i did not powur that gas or light that fire. lastly, he says, i will never find peace again and my soul is torn. at no time during that statement did i hear him ever come out and say, i am sorry for what i did. >> i remember after his accomplice steven hayes came out at his sentencing, he was sentenced to death. we saw william petit come out to the courthouse steps. he spoke. did he speak today, brian? >> he actually did speak prior

to komisarjevkys's statement. he said, i lost my family, my home, my best friend. we were robbed of all this in a heinous manner for what? money. he left right after he made his impact statement, leaving joshua komisarjevsky to read his statement to the media. no one was there from his side when he read his statement. now police said a would-be disaster of an attack deadlyer than columbine. >> two teenagers accused in this violent plot targeting their own classmates. we're now hearing of this escape plan and here's the man who wrote this book called "why do kids kill?"

did these two teenagers fit the profile? stay here. an accident doesn't have to slow you down. with better car replacement available only with liberty mutual auto insurance, if your car's totaled, we give you the money for a car one model year newer. to learn more, visit us today. responsibility. what's your policy?

two students are plotting to blow up their own high school in roy, utah and they might have gone through with it, police say, if they hadn't tipped their hands. take a look here. this is the older suspect. this is the face we can show you. this is 18-year-old dallin morg morgan. he is already free on bond. police aren't naming the other suspect because he's only 16. he is still in custody, and investigators say these two had an elaborate plan by make ag bomb, setting up maps, a surveillance camera, blind spots. they were even thinking about stealing a plane afterwards to escape to another country. but this whole plot started to

unravel when a fellow student spoke up. the student came forward, was on the receiving end of several alarming text messages allegedly sent by the 16-year-old indicating an attack was coming. here's one of those texts. quote, if i tell you one day not to go to school, make damn sure you and your brother are not there, end quote. and if any of this sounds reminiscent of columbine, it's no mistake. they're supposedly both a big fan. peter ham by is here to talk about school shooters. from the information you have, do these two teenagers fit a pattern at all? >> they certainly do fit a pattern, but it's not the typical school shooting or bombing, only because there were two of them. but there have been twice other times that two students teamed up both at columbine and in an attack in jonesboro in arkansas in 1998.

so students have committed attacks before, but it does make it different than your typical attack. >> what happens in a young person that sends a child down one path versus another, a path of destruction? apparently one of the teachers described the 16-year-old as a young einstein, very smart. why go this direction? >> there usually have been many factors that influence a kid to commit a school shooting. sometimes it's more genetic, it has to do with their personality or with significant mental health issues such as schizophrenia. in other cases it's more environmental. some school shooters have come from really broken homes, have a history of physical abuse, their parents were substance abusers, in and out of jail and so on. so some cases seem more environmentally influenced and others seem more about just who the kids were as people. >> that makes me think about psych 101 and nature versus in

your nurture. another quote, i just don't care. i'm pretty much a lying, cheating, manipulator with everyone except seven people. everyone else is just a piece. what do you think about that? n n >> when i hear the lying and cheating, it makes me think of haof eric hair rorris, who was good manipulating people. >> eric harris and dylan klebold, the two who pulled off the columbine shooting. the 16-year-old so entranced by the columbine shooting hopped a

plane, flew to denver and questioned the principal as if he were doing a story for a school newspaper. >> columbine established itself as kind of the prototypical school shooting mainly because of its attitude. and eric harris conducted him as a manipulative, secretive, and yet charismatic, in his view, and influenced other school shooters. so eric harris became the role model, in this case, to try to outdo. >> thank you to that student, whoever he or she is, who shared those text messages with police, or we would be having a very different discussion. peter, thank you. 55 pounds of cocaine found inside the united nations!

plus, where it came from. we had been getting these 911 calls before demi moore went into the hospital. the caller you're about to hear is next to her through this. how close did this asteroid come? it ranks pretty high. i'll tell you about that next. tourism season in years. all because so many people came to louisiana... they came to see us in florida... make that alabama... make that mississippi. the best part of the gulf is wherever you choose... and now is a great time to discover it. this year millions of people did. we set all kinds of records. next year we're out to do even better. so come on down to louisiana... florida... alabama... mississippi. we can't wait to see you. brought to you by bp and all of us who call the gulf home.

if it's interesting and happening right now, you're about to see it in rapid fire. let's go, beginning in iraq. a suicide car bomber targeted a shiite funeral procession today. in total, 31 people were killed. the blast happened as mourners

passed this outdoor market in baghdad. they were on their way to pick up the bodies of three relatives who were shot to death thursday night. 60 people were wounded in that explosion. president obama wants more middle class families in places like michigan to be able to send their kids to college. he told a packed crowd in ann arbor today that he wants federal spending on perkins loans to increase from 1 billion to $8 billion. >> we are putting colleges on notice. you can't keep -- [ applause ] >> you can't assume you'll just jack up tuition every single year. if you can't stop tuition from going up, then the funding you get from taxpayers each year will go down. we should push colleges to do better. we should hold them accountable if they don't. >> candidates, cocaine? in the united nations mail room more than 35 pounds were found in these hollowed out books shipped to mexico. the cocaine was if a bag made to

look like a diplomatic pouch. authorities are investigating and no word on who was to get said pouch. remember the barefoot bandit, the guy who eluded police for two years? he was sentenced in a seattle courtroom, six years in prison. he was arrested after crashing a stolen plane this the bahamas and trying to escape in a stolen boat. his criminal adventures, shall we call them, often done without shoes, barefoot, attracted a following of 50,000 facebook fans and a movie deal. and we have what amounts to a cosmic near miss today. an asteroid about the size of a school bus, was 50,000 miles. we were never in real danger, but it was one of the closest

asteroids recorded. latitude 68 degrees north. that's pretty far up there. chad meyers, looks like an animation. this is the real deal. northern lights. could you imagine looking out your house and seeing the green in the sky? >> i've seen it one time. >> oh, wow. >> i was in detroit lakes up in minnesota and i was fishing and we were watching this overhead and it was mezmerizing. it looks just like that. i have a couple reports it headed all the way to marquette, michigan. but just the bottom of the horizon. tell you what, we're getting into an active solar season now. maybe there will be northern lights into the middle of 2013. we may even see them down here in the middle latitudes of the u.s. a little north in ontario, very bright young men hooked

$180 in helium and hooked this guy up 180 feet in the sky with a parachute and a cell phone for gps tracking. it went 70 miles down range after a 97-minute top to bottom flight. it landed. they finally found it later on and they have all this awesome video. >> they took these pictures. >> and lego man now 80,000 feet in the sky. that's about 15 or 16 miles. >> chad, thank you. coming up next, we're going to play part of the 911 call just before demi moore was rushed to the hospital. also this. >> i never was in trouble for it. >> okay. >> this is chilling video of a killer denying a little girl's murder. he did later admit to doing it and killed himself behind bars. we now have this interrogation video that was shot just 24 hours before police charged this

man with the unspeakable crime. you're going to hear what he said and what it reveals, next.

. denials and lies from the maintenance man who murdered a 7-year-old girl. just-released video shows this guy, ryan brunn, before his polygraph test denying the murder of the little girl. she died january 2nd. she was found days later. she had been beaten, raped and thrown into a trash compactor. brunn repeatedly denies raping her. >> did you cause the death of that girl? >> no. >> did you participate in any way of disposing of that girl? >> no. >> do you know for sure who caused the death of that girl? >> no.

>> watch in this next clip how calmly brunn describes news reports of dareli's death. >> i didn't participate in any way of causing the death of that girl. in other words, did you have anything at all to do with it whether you were a party to it, did you help somebody or did you do it yourself? >> no. >> did you cause the death of that girl? g >> no. >> have you heard, and i'm a little bit behind on the news releases and stuff, too because i didn't get a chance to see the news. did you hear how she died? >> no. >> did you hear anything when they found her? >> no. >> do you watch the news? >> i watch some of it. >> what did they say on the news? >> they found her body in an apartment complex. >> did they say anything about her? >> they said she was actually abused. >> last week he pled not guilty

and hanged himself in prison two days later. ever since actress demi moore was rushed to the hospital on sunday night, there has been an army of speculation as to why. they have just released the 911 call made from demi's house. it shows how much trouble moore was in medically and, hence, the star's troubles run deep. >> tell me exactly what happened there. >> okay, she smoked something. it's not marijuana, but it's similar to incense, and she seems to be having convulsions of some sort. >> right now is she awake? >> semi-conscious. barely. >> is she breathing? >> yes. >> she overdosed on -- >> and she's convulsing. >> don't put anything in her mouth. did she smoke anything?

>> she did, but it was accidental. >> she tells the 911 dispatcher that she is a friend of demi moore. >> is she breathing normally? >> no, not so normal but more sort of shaking. burning up. >> what did she take? >> some form of painkiller and she smoked something. she's been having issues lately with some other stuff, so i don't know what she's been taking or not. >> is she able to respond to you? >> can you hear me? she's squeezing hands. she can't speak. >> has she done this before? >> i don't know. there's been some stuff recently that we're all just finding out. >> demi moore announced last november that she is ending her six-year marriage to ashton kutcher. now this. i really can't believe something like this happened at a daycare. >> a daycare. a man in charge of watching other people's kids duct taped a

child to the floor. you're going to hear the reason. the parents, they didn't even know. wait until you hear how the family did hear about it. we can do better, next.

sometimes we run across cases and stories that make you think, what were they thinking? like this one. a daycare center, taking care of children is a tough job. and young kids don't understand why they shouldn't do something. you have to keep your frustrations in check. that didn't happen one day last october in this center in ludlow, kentucky. an 18-month-old boy wouldn't go to sleep at naptime, so alicia lyons allegedly took matters into her own hands. she duct taped him to the mat

and then duct taped the mat to the floor. >> she is causing cruel confinement to a child. >> even though the duct tape incident happened last october, the boy's mother found out about it this week when another worker mentioned it to her. the daycare center said lyons first denied the allegation and then admitted it happened. the center said it fired her and went right to police and the kentucky inspector general, all serving to remind us when it comes to our children and the people who help us take care of them, we can do better. shifting gears. listen to this one. a grown man asked for a restraining order against a fourth grader. find out why and whether he actually got it. speaking of kids, have you ever watched "toddlers and tiaras"? a woman is suing the media for sexualizing her daughter. sunny hostin, fire up the media.

we're on this case. dinner? candles? i wanted it to be special. oh, what's this? it's progresso's new loaded potato with bacon. mmm, it's good. honey, i love you and... oh my gosh, oh my gosh.. look at these big pieces of potato. yeah but honey, i love you and... is that what i think it is...it is... it's bacon. honey look. [ male announcer ] progresso rich and hearty...

4 new flavors, you can lose yourself in. what's that? big piece of potato. [ male announcer ] progresso. you gotta taste this soup.

listen to this. a restraining order has been issued against a ten-year-old boy in california. ten. fourth grade. he was requested by the father of this boy, who is also 10 and in the same class at school. >> a kid pulled a knife on me and threatened to kill me. and i said, what? i said, did you tell the teacher or principal? and he says, it was in class. >> sunny hostin is on the case,

and just out of the gate here, how often is a restraining order issued against a child? >> you know, more often than you would imagine, brooke. >> really. >> you can get a restraining order against anyone under the age of 18. here we're talking about a 10-year-old, but what if we were talking about a 14-year-old or 15-year-old or 16-year-old. we see a lot of cases of bullying, and i wonder, brooke, if this is perhaps the extra step needed for parents to utilize to stop bullying in its tracks and perhaps protect their children when schools aren't doing the right thing and not doing their job. i actually, and i know i'm coming down on this in a way that most people wouldn't think i would. i say bravo to the father. i think it's using a tool to protect your child, and i like it. >> okay. so you say he should be taking this kid's threats seriously. what about the school, though? where do they fall in terms of responsibility now? >> well, it's interesting,

because that's sort of the first line of defense, right? you say that your child is being bullied on school grounds, well, the school is supposed to do something. this father felt the school didn't do enough, didn't take this incident seriously enough. and let's face it, we're talking about a child brandishing a knife and threatening that other child. now the school is in a position to having to enforce that restraining order, meaning the children can't be within a certain distance of each other. i have to tell you, i think with the epidemic of bullying we're seeing, perhaps this is a tool parents can use to assist them in protecting their children. bravo. >> bravo, you say. i don't know -- we'll get to this. one of the mothers on the reality show "toddlers and tiaras" suing tmc, full transparency, time warner. the mother said these three web sites wrote articles in a brazen

attempt to sexualize her daughter. this started with elizabeth barrett singing along with the hip song by aflo. the title of the song is "i'm sexy and i know it." so, sunny, i guess the question is -- i'm assuming, do we know it was at the mother who had the child sing the song in the first place, and the next question is why is the mother suing exactly? >> well, i've been watching this video over and over and over again to try to figure out exactly what happened, and i got a copy of the lawsuit, brooke. and yeah, apparently not only was the mother there and kind of egging it on, apparently the mother set the whole thing up with the child's publicist. and so now she's suing all of these companies for libel. and what's so interesting about it is the very definition of libel is that it has to be

false, it has to be a false accusation. i don't know. i just watched the video. our viewers just watched the video. you watched the video, the little kid is singing "i'm sexy and i know it." this is just, in my view, borderline frivolous. not only is the child a public person because her mother has put her out there on reality shows, it's clear for everyone to see that she was singing those lyrics and sort of dancing in her chair. so i've got to tell you, you know, again, i put my mommy hat on, brooke. you can't, you know, do this to your children. >> i know mom has released a statement, a lengthy statement here. what does it say? >> well, it is a lengthy statement, and interestingly enough, she says, we have done nothing to exploit my daughter. paj engeants are a part-time ho for isabella, not a career

choice. we try to show the positive side of pageants. i don't know about what everyone thinks, brooke, but i think this could be considered exploitive, this sort of pageant business. she's on a reality show. she has -- this little girl apparently has a jewelry line that she sells. this is a public enterprise at this point, and for a mom to -- >> i would love to know what our viewers think. write me a line. i'm curious. thanks, sunny. we'll see you back monday on the case. appreciate t. how does this sound? free plane ride, free housing? we'll hear brianna's report. plus, we have some advice about your money and your mortgage. stay right here. people with a machine.

time now for the help desk where we get answers to your financial questions. melissa is a personal financial expert and askthemoneycoach.com. betsy wrote in, my husband and i are both self-employed. our income is 30 to 40,000 a year. we have about 500,000 in investments. how can we get a low rate to refinance? >> a great way to refinance is to shop around. you want to go to a site called hsh.com. hsh is a free mortgage comparison site. essentially you'll be able to get lenders to compete for your business. having that 500,000 on hand will show a lender that you have cash reserves. the income is modest, but you really do need to make sure that your house has the sufficient amount of equity in it. if it doesn't, in order to do

the refinance, you might have to take some money maybe not from the investments but other places and pay down the loan if you need to in order to get that refi done. but it's a good place to comparison shop. >> the refi will also cost several thousands dollars. k. p. wrote in, my wife and i need to relocate. i have a credit score in the low 500s and have never been late on a mortgage payment. the house is $25,000 under water and i can't continue to afford paying the 7.25% interest. is it better to try a short sale or should we walk away? >> this is a gut-wrenching question, because with that credit score in this kind of tight environment, it's going to be nearly impossible to get a positive outcome if he continues on the refinancing path. my personal feeling is i prefer to see people try to short sale. it's a tough moral judgment, but i feel for a variety of reasons, first and foremost, impact on your credit score, but also the way people feel, a short sale is

the better way than walking away. >> if you want answers by our experts, just send us an e-mail to cnnhelpdesk @cnn.com.

we have been hearing a lot lately about the bank accounts of these republican presidential candidates, but what about the money they could earn if they win the presidency and beyond? brianna kheiler takes us in depth on money and politics. >> reporter: being president pays. $400,000 a year, in fact. there is free transportation on and off the ground, free housing and other perks like a chef. when a president leaves the

white house, he is still on the government payroll, receiving a pension of about $200,000 a year. health care, paid official travel and an office. rent on jimmy carter's atlanta office is about $100,000 a year according to the latest figures available. george h.w. bush's houston digs, 175,000. and bill clinton's harlem office, more than half a million dollars. but these taxpayer funded benefits are nothing compared to the big bucks presidents rake in writing books. bill clinton's "my life" netted him an advance of $15 million, believed to be the biggest in history at the time. george w. bush wrote "decision points." >> after the presidency, my life went from 100 miles an hour to zero, and the book gave me a focus and a project. >> reporter: it also gave him $7 million for the first million and a half copies.

jimmy carter wrote 14 books. >> he was broke when he came out of the white house. if you can write or you can write with someone else, you can write a book and make a great deal of money. >> reporter: then there's "dreams for my father." president obama wrote it in his 30s. >> before this book started selling about four years ago, we were living in a condo, myself, michelle and our two girls, and we were -- we had two cars but one of them was kind of beat up. >> reporter: that book flew off shelves when he ran for president. the obamas went from middle class to wealthy and made several million dollars. but for the biggest payoff for not too much work, speeches are the way to go. and when it comes to ex-presidents, bill clinton is the reining king of the podium. >> i never had any money until i got out of the white house, you know, but i've done reasonably well since then. >> reporter: that's quite the understatement. since 2001, clinton has earned

more than $75 million giving speeches to corporations and organizations around the world. since george w. bush left office, the center for public integrity estimates he's made $15 million for speeches. but all that money raises questions. >> i think that the american people think that american politics is all about money, and this certainly doesn't change their view about what presidents have after they get out of office. >> reporter: in 1989, right after president reagan left office, he was skewerred for accepting $2 million for two speeches in japan, then an economic foe in the united states. some presidents are not rich. harry truman, for instance, couldn't afford to answer his mail when he left the white house, and that's partly why pensions were introduced to presidents in the 1950s. if we look at one of the republican front runners, mitt

romney, if elected, he would be the third richest president, if you account for inflation, behind george washington and thomas jefferson. brianna kheiler, cnn. before we talk about curiou questions they have is what happens in the commercial breaks, and you say that's kind of a bathroom break time, drink a little water. my question, though, is, these candidates, do they talk to each other in the commercial break? look at each other? >> sometimes they do. when there were eight candidates, the first two debates i moderated, they were talking to each other. as the field narrows, it gets a little bit more intense. newt gingrich, for example, he goes to the front of the stage and he sometimes walks down and talks to calista, his wife, mitt romney, they're not really talking to each other. i talked to him a little bit just to see how they're feeling, see what's going on. they're all freshening up a little bit. they go in the back -- >> staying in the zone.

>> they come out, and that's that. >> okay. rick santorum coming up in the 4:00 hour. >> i thought you were going to ask me what i do during the breaks. >> well, i imagine you're just, you know, studying up on the next questions and being very focused. >> i'm focused like a laser beam. on my next series of questions. >> exactly. >> so important i've got -- >> i knew that already. >> yeah. >> of course. . >> so rick santorum, you're working on those questions for him next hour? >> yeah, i'm focusing like a laser beam right now, and those questions, as well. seriously, you know, he's in it to win it, he says. he's not dropping out. he's not holding back. beginning part of the debate last night, i thought he was holding back a little bit because maybe he wanted to be a vice presidential running mate or get a cabinet position, wasn't going to go full tilt against newt gingrich or mitt romney, but you know what? he really did -- he went after both of them pretty hard. so he's not interested in a job, he's interested in becoming the republican presidential nominee. we're going to talk to him, and

we'll see what's going on on this important day before this very important day after the debate, but before tuesday's primary. >> good deal, wolf blitzer, we'll see you in a couple of minutes on the "situation room" from jacksonville. is it possible to tell whether you have a concussion? how do you protect your family when it comes to head injuries? dr. sanjay gupta is back in the house. and about to run a cognitive test on me? as he laughs and walks toward me with a brain. stay tuned for this. i saw that over there and i was like, sanjay's been here. that's when you know. but first, a quick look at what's behind the scenes on the newscast. this is what we do each and every friday. i answer your questions. here's a little piece of our week wind down. >> well, well, mr. j.k.usa, john king asks, where do you hide the uggs when you go on tv? >> he knows not only do i wear my uggs to work sometimes, but on primary night, i'll kick them off right before i go on. they're comfortable and

sometimes they hide behind the desk. and christina and i are going to tampa for the big florida primary. looks like monday, tuesday, wednesday, 2:00 live from tampa. we're paying for all spill related clean-up costs. bp findings supports independent scientists studying the gulf's environment. thousands of environmental samples have been tested and all beaches and waters are open. and the tourists are back. i was born here, i'm still here and so is bp.

we're taking the show on the road. monday, tuesday, wednesday, we'll be live in beautiful tampa, florida. we're going to sit down with super successful retirees who are thriving in this economy. and i want to ask them how they do it. tuesday i'm talking with a young woman who is fighting for her right to live in this country. we are highlighting immigration and specifically the dream act with her and her family. and then all week because this is what we like to do on the show, we're going to go behind the scenes of these massive republican presidential campaigns. i was particularly curious as to how do they pick the music at those rallies? and how campaigns manipulate the room to make the crowd look larger and the craziness surrounding the candidates after the debates. this week, dr. sanjay gupta has been telling us about the problems these athletes face, men and women, from the bone-jarring hits they receive. he's back today to talk solutions, you know, parents they want their kids to play sports, but protect the noggin. >> and i love football, as well. so the reporting was really

about the solution for some of this. athletic trainers, for example, you and i talked about this. you need somebody who can recognize a concussion. biggest problem is to let someone play who has had a concussion. also, you know, simple things like looking at practices and realizing the vast majority of head hits in football and most sports come about in practices. after a player has mastered the particular skill, ramming their head 30, 40 times every practice. >> soccer you were saying, as well. >> two-point stance versus three-point stance. two-point stance forces you to tackle with your chest, your arms, and your hands. and also helmets, something we talk about quite a bit, helmets are important, but they're not -- they could provide a false sense of comfort, as well. they're not going to protect against what actually causes concussions. they can prevent a skull fracture, but what happens in a concussion, i have my brain model here, is that the brain is actually moving back and forth in the skull. so brains running down the field

suddenly stops because of a hit, brain keeps going in the skull and then back and forth. think of like an egg yolk inside an egg shell. you can prevent that egg shell from cracking, but what's the yolk doing inside? that's why helmets can't do everything as far as preventing concussions. >> what do we do in thinking of this moving back and forth. you can't keep it in one spot? >> it's tough to do. you want to limit the number of hits, obviously, which is the thing in practice and everything. but also this idea of leading with your head, you know, tackling with your head, instead, moving the head out of the way. again, doing the two-point stance, you're tackling with your body as opposed to your head. and that's something worth changing, i think. >> two minutes to go, and i'm hearing that i'm taking the memory test? it's been a long week. >> the point is -- as you might have expected, you watch football, these players want to play. someone says, look, you're benched, you've got to sit on the bench, they don't like that so they say, well, i'm feeling fine, right? >> right. >> about half of players will

basically manipulate or frankly lie about their symptoms. >> to get in the game? >> to get back in the game. what a lot of schools are doing the cognitive tests a the the beginning of the season, get a baseline, and if someone has a hit and you're not sure if they're back the normal again, you test them again. i want to give you a glimpse here. you can play along. >> we've got 60 seconds. >> take a look at this list. try and memorize that list as best as you can. >> mirror, stove, parent, forest, ladder. >> now -- and again, keep in mind what would happen if you were to have a concussion and you said, look, i'm feeling fine, everything's good, we weren't sure about you, we'd say, you know what? let's see. and as part of that, we'd put up a list similar to this list, for example. and now out of this list, see if you can find the words i gave you in the first place. >> mirror, stove, forest, parent, ladder. >> there you go. flashing red, see if you're right, and you are. so you pass the
