California. Thousands are gathering, you can see these live pictures, to mourn the victims. Six students murdered during a killing rampage friday night at the university of california santa barbara. Janet napolitano, the uc president and former secretary of Homeland Security is going to be speaking, along with the father of chris martinez. He was Elliot Rodgers final victim, shot, murdered at a deli. In the random horror, the five other victims included rodgers two roommates and a friend who was just visiting. Police say rodgers stabbed them to death in their apartment. From there the 22yearold got into his bmw. He drove only two blocks to a Sorority House and murdered two more women. Then he drove to a deli, where this Surveillance Video captures the barrage of bullets that killed martinez. Rodger kept driving and shooting at random people before police say he took his own life. And investigators say rodgers murder rampage was a twisted attempt to get revenge against people he say had rejected him. His frustrations were detailed in youtube videos like the one youre looking at right now, and a 137page manifesto. Kyung lah is out front in goleta, california, where the memorial is taking place. We can see all the students behind you, kyung. I know there are many thousands coming there tonight. The cassity for this stadium, erin, is 17,000. It looks like theyre going to hit it. It seems like the entire university is here, the entire town. And this is just a snapshot of how this has affected everyone who goes here, the schools, the university, the people who live here. They say they are grieving. They need this so they can try to put the pieces back together. They have also come to hear chris martinezs father, who has a potent message to share with this crowd, as well as everyone in this country. Who would have dreamed that this could have happened to us. Reporter not to my child, thought richard martinez. His son, chris, just 20 years old, a ucsb english major went to the iv deli mart when bullets flew into the store. No one thinks its going to happen to their child. I would never have thought chris would die in this way. How would i know . How would i think of that . No one would think that, that your child would die at 20 in front of a deli. Reporter what could a father do . He did this. Our son Christopher Martinez and six others are dead. It was an extraordinary moment when you walked into the news conference. They talk about gun rights. What about chriss right to live . Reporter very unexpected. Why did you do that . Because i realized that people are only going to be interested in this for a short time. And to honor the memory of my son, im determined to take advantage of the limited amount of time that we have to talk about this. Reporter and what he wants to talk about is how we got here. Another gunshot wound by the iv deli mart. Code 3. Reporter investigators say the gunman suffered from a Mental Health issue, yet he still owned semiautomatic handguns and hundreds of rounds. All purchased legally, to the frustration of this father, a veteran and former gunowner. I cant tell you how angry i am. Its just awful. And no parent should have to go through this. No parent, to have a kid die because in this kind of a situation, what has changed . Have we learned nothing . Reporter learned nothing from newtown, he says. 20 children and six adults shot and killed at sandy hook elementary in connecticut. President obama pushed for tougher federal gun control laws, expanded background checks. But that failed in the Senate Despite overwhelming public support. I think the vast majority of people in this country favor some type of reasonable gun control. But every time somebody mentions gun control, they get this strong reaction from a small vocal minority and the politicians cave. Every time. Reporter he says it will probably happen again this time, but this father wants washington to hear this. Where is the leadership . Where in the frigging politicians that will stand up and say we need to do this. Were going to do something. Those gutless bastards have done nothing, and my son died because of it. Its outrageous, absolutely outrageous. Reporter and its not just gun rights that mr. Martinez is talking about. He says this is as much about Mental Health and the lack of this countrys ability to take care of those who need help. Erin . Kyung lah, thank you very much. And that stadium fits 17,000. You see the students walking in now. They suspect it will be completely full tonight. Elliot rodgers history of Mental Health was not a secret. His parents were frantically searching for their son after receiving the chilling manifesto and seeing this youtube video. Tomorrow is the day of retribution, the day in which i will have my revenge against humanity. Outfront cnn legal analyst paul callan and mel robbins and dr. Guardier. You just saw that video. This is a young man, his mother saw some of his disturbing videos this spring in april, end of april, just a month ago, called police. They went to his apartment. He convinced them it was a misunderstanding. Is this something is that could have been prevented, or are these things that some people do, and most of the time they dont turn into anything . Well, first of all, the cops did not. And im not pointing fingers. But they didnt connect the dots, that there were previous contacts with the police officers. So if in fact they had known about the two previous con techs when they went do to do the welfare check, then they would have put it all together and said wait a minute, there is something not right here. Secondly, what we see in many states, there are not laws that state that you have to have a Mental Health expert go along with Law Enforcement to do this check. So here is a situation where you had Law Enforcement who really were not experts in any way in Mental Health, and therefore could have easily been fooled. So do you think, paul, this could have been prevented, given what he is saying . This is not the first time that police have been called . I dont think it could have been presented. The talk for instance about gun control. Gun control wouldnt have stopped it. No. The gun was legally obtained. And he killed three of his victims with a knife. He is the kind of kid who would have used gasoline probably to douse the Sorority House. He ran somebody over with his car. Its not about gun control. In terms of Mental Health availability, he is a rich kid. His parents could have gotten a psychiatrist for him. In fact, he had a therapist. They could afford to give him a hospital bed. So its not about providing Mental Health for the disturbed. But nobody came in, mel, and said this hits that bar. Yes. And thats the problem, erin. Youre nailing it and saying exactly what everybody at home is thinking, which is what do you mean . You have a kid that rants on like this and the cops show up a month before and they dont take him into custody . Part of the problem is the two prior times that the police were with this kid had nothing to do with Mental Illness or any concern. Scuffles with the roommates. Second, youve got a system in place, and you see that father. Its heartwrenching. And he is talking about guns. And i think the problem is the laws around Mental Health. We have a system in this country where the mentally ill have selfdetermination. They get to determine what happens to them. So the police show up. Theyre told by a professional Mental Health worker, theyre told by the parents that this kid is threatening violence and he is threatening suicide. That there is a youtube video. They dont see the youtube video. They have credible account from the parents. Hold on. The parents were never told those things. Thats not true. Specifically. Im talking about the april 30th visit. They total the police. Let me finish for a second. If the cops knew that, then the cops are wrong and they had an obligation to lock him up. Let me tell you this. 20 of the American Public suffers from some kind of Mental Illness. 26 . 26 . All right. So mel robbins wants to create some type of a police state where were going to lock up everybody who is saying things that we dont like this. Is a very, very hard decision. This is a difficult decision. I want a different standard. I represent psychiatrists in these cases. And theyre tormented in these cases because sometimes even when he has admitted to a hospital, then a psychiatrist has to say do we keep him indefinitely, or can we send him holme to a stable home environment . You dont get to put someone in for 72 hours. Ive talked to the mother of a child who has threatened to kill her and siblings. Right. And the child wanted to have more care, and they continually release them. They send them home after the 72hour hold. Its not designed to work with it well. We know most of the Psychiatric Hospital beds are gone now. Insurance doesnt want to pay for Mental Health. So this kid wouldnt have done this, it sounds like youre saying, okay, fine, maybe there have would have been a 72hour delay. But it would happen. A 72hour hold, if they said look, lets take him to a hospital, which is what they should have done. Already treated by a therapist. He is already in therapy. But he wasnt taking his medications. Thats a major issue. Number one, they may not admit him because he has to be a danger to himself or others. He was clearly a danger to himself or others, but they couldnt see it. Yes. And secondly that. Discharge him. Once they discharge him, he he is back out there again. Thats why many psychiatrists and psychologists will not just say get someone hospitalized because theyre talking dangerously, because theyll lose that patient. Theyll lose the patient. There are two cases when people talk this way, nothing happens. No, it doesnt. Lets just be realistic. Is. How can you . You have no place to send them. I was looking at the stats here. In 1955, we had x number of beds available in psychiatric facilities. Do you know we only have one of the five beds that were available in 1955. There is no place to send these people in the united states. Okay. So if the police in a well check, so theyre showing up to see about the wellbeing, if they had the authority to be able as part of that check to look around the house, to check out the cell phone so now youre going eliminate search warrants . Yes, yes. [ overlapping dialog ] you lock up anybody thats not true, paul. Dont put words in my mouth. If a parent says we think our kid is crazy, we think he is going to hurt someone, there is a youtube video, we better do something about this. Lets get him checked in the hospital. Instead, they said not only was he okay, but he was a wonderful, beautiful person. They got duped. They got duped. Because of the standards. Its not the cops. Its not the cops. The cops are not at fault here. Please, we do want everybodys feedback on this and what you think should have happened. Outfront next, months after flight 370 vanished, the raw satellite data.

Thanks to the backing of senator ted cruz, the tea party is expected to seize victory. But its a very different story in mississippi, where Chris Mcdaniel, who is often called the next ted cruz was supposed to sail to victory, be the tea partys best hope of bringing down an incumbent in the gop. But now his campaign is wrapped up in a downright bizarre scandal. Dana bash is outfront with the story. Reporter a conservative blogger is in jail, arrested for breaking into this mississippi nursing home to photograph u. S. Senatored that cochrans ailing wife, suffering from dementia. Its the worst. Reporter in gnaw ad, cochrans Campaign Points fingers at his gop challenger, Chris Mcdaniel. Posting video of senatored that cochrans wife in a nursing home . Had enough . Reporter and it gets even deeper in the mississippi mud. Cochran supporters argue the reason the blogger took his wifes picture was to feed questions about cochrane and longtime aide kay webber, who has traveled extensively with the senator on the taxpayer dime. Cochran calls it part of her job and suggestions of anything untoward sexist. This republican primary was supposed to be about the struggle of ideas within the gop. Chris mcdaniel. Reporter a young tea partybacked upstart challenging a fellow republican for being out of touch and too entrenched in washington after 36 years in the senate. Now Chris Mcdaniel is fending off questions about whether his campaign had anything to do with photographing his opponents sick wife. Our campaign had absolutely no connection to that whatsoever. Reporter you personally, when did you find out about the breakin . Were going focus on his record right now. God bless the tea party. Reporter mcdaniel would like to be the senates next ted cruz, stick to principle, compromise be damned. I am not going to washington, d. C. To be a member of the cocktail circuit or to make back room deals. Im going up there to fight and defend the constitution. Reporter talk to mississippi republicans and democrats who say come on,ed that cochran has been there a long time, but he is a good public servant. I say one fight senator cochran has put out against barack obama. Name one time he has raised his voice in defense of conservatism. Reporter for the Tea Party Movement after a string of primary losses this year, mcdaniel has been their great hope, the best chance of toppling a republican, especially after this cochran stumble. The tea party, you know, is something that i dont really know a lot about. Reporter millions of dollars pouring into mississippi against cochran come from a whos who of Tea Party Groups nationwide. Mcdaniel says he is a lifelong republican. Reporter but like other republican incumbents, this year cochran and his allies are fighting back, painting mcdaniel as extreme and inconsistent. After four decades in washington, cochran has loyal supporters like this democratic mayor. Youre a democrat. Yes. Reporter and youre supporting senator cochran . Yes. Reporter why is that . One is that i understand politics, and i understand what is needed in a state. And he is what we need in washington, d. C. To stay as long as he wants to stay. Reporter at this point, cochran is trying to avoid unforced errors, going to headscratching extremes to avoid talking to us. We tried to catch cochran after this event. But when an aide came out and saw us, they did a bait and switch. The car they told us cochran was getting in screeched away without him, while he snuck out another door to a different car, leaving reporters like us in the dust, unable to talk to the senator. Dana, this story is incredible on every level, including that. Going to those lengths to dodge you . I dont think im that scary, do you . Look, this is all about making sure there are no forced errors. It is do no harm that is the most important thing pour the cochran campaign. Thats why he isnt talking to anybody at this point. The gop primary a week away from today. I can see in that interview you did with mcdaniel why they would call him the next ted cruz. But obviously, trying to this whole link possibly to taking pictures of senator cochrans wife in a hospice is distasteful at best. Does mcdaniel still have a shot at winning . When i talked to him today he says they feel confident, they feel good. But i have to say that republican sources who i think are pretty good in washington who are fighting really hard for cochran insist that he is going to survive. He is going to stay in the senate. And they are really hoping that happens for a lot of reasons. But they hope this deals another blow to the tea party. Well see a week from today, though. Thank you very much, dana bash in biloxi, mississippi tonight. And still to come, a shocking new weight loss study. Well tell you which beverage researcher says will help you lose weight.
