let's bring in criminologist and cnn contributor casey jordan. on that's come in so far, but what can you discern from the information we have and what else are you going to be looking for? >> well, just knowing that he was a male student 20 years old really does fit the profile of the campus shooter. they're not confirming that he was a student there, but i would be absolutely shocked to find out he was not. he surely attended classes there perhaps in the past, maybe now. and while there had to have developed some kind of beef with the fellow students or the administration or some kind of discontent that made him decide when he was going to act out on these fantasies of violence this is the place he's going to do it. >> you regularly as a criminologist study the behavior of gunmen in cases just like this one. all we know is that he's a 20-year-old male. and obviously he committed an act of horror. and obviously according to police he got into a shootout with police. what do you make of that? >> this is a guy who knows he's going to die and is emp

up front now, our law enforcement analyst harry houck along with casey jordan. online conversation that deb is talking about, if this does, indeed, involve the shooter, other people then were involved, were aware. i guess is the right word involved? could people have been involved? what's the culpability? >> well, it depends. if he went on, let's say, this chat room with a different name like abc123? how would they have known. >> because of anonymity. >> but did he say "i'm going this school to attack it at 10:30 in the morning," if that happened someone could have notified the police and have said "there's a possible attack. people are faulking about it online." that could have been done and we don't know what the conversation was and how detailed he got. >> now you know some of the people in the conversation calling him a pathetic loser, there were supporters and detractors but others even at one point suggested what weapons to use. how common are conversations like this out there? >> in the deep web they're more common than you think because there are places

casey jordan, why does this keep happening? there are not enough hours in the day to really answer that question, except that the pattern that keeps being revealed is is it's mostly males, predominantly white in their 20s and all feel maligned by life. i don't want to call them losers, but they have a number of failures with school can, relationships, jobs, and they want to scapegoat all their failures on to someone or something else. and sometimes they pick a a microkoz m of society and you can't get focused on whether they hate women or blacks or religious people. it's that they are looking for anyone and anything to external liez the blame on to. >> which is what they do. they want notoriety. >> once they pull off this violent act, their power will be solved even if they don't live through it, they will experience power and have the last word once in their lives. >> but he's dead. >> they have this tom sawyer concept that they are going to hover over their funeral and watch cnn and say, yeah, i did it. they don't realize onc

i want to bring informer fbi profiler james fitzgerald and casey jordan. the shooter could have left this flash drive, right, all of these writings for the police. he could have done it any way he wanted to do it. he chose one person, one randomly, the one with the glasses, the one lucky one, he called them. why did he do that? >> many time these types of shooters choose representationalt representationaltar targets. they also may choose a representational person's life to spare and this person, matthew, perhaps looked like someone from the past, perhaps they had a casual glance to each other walking down a hallway a few days before, maybe sometime in the past and for that reason this was the one person that perhaps the shooter related to and said, you know what, you're going to be the one i spare. i cannot only take life but i can allow life to live and you're going to be the one. what better power trip than someone in that particular situation. >> it's like playing god. you just heard matthew's mother say that the shooter locked eyes with matthew. what d

i want to go now to profiler james fitzgerald along with casey jordan, criminologist and also a former.s. marshal. obviously the key word that deb said that i want to get to, how ordinary he was, that you did not see these red flags. we don't know much. some of the things we know, his former neighbors in california said he lived with his divorce mother, incredibly close to her, he was fiercely protective of her, even from minor annoyances like cockroaches in the apartment. what do you make of the relationship with the mother? >> well, today we would graduate from the helicopter term and graduate to a lawnmower term. she admitted he had mental issues. and what she does is clear the path for his success, make excuses and, in the process, enables his behaviors, his fantasies, maybe he rules the roost, he tells her what to do. but that dynamic, that enabling of her son to have this other world that nobody else has seen, to the outside world he looks ordinary but he was really invisible and that's why he felt completely persecuted and wants to scapegoat on to everyone else. nobody noticed h

casey jordan, appreciate it. >>> and up next, why did a missing american ship sail directly into the eye of a hurricane? and how can a ship that size just vanish? families holding out hope their loved ones survived. >>> plus a a top u.s. commander testifying about the strike that killed doctors and children inside a a hospital. hear his admission about that decision. >>> and donald trump goes off during a cnn interview about everyone asking him when he's going to drop out of the race. doesn't he have a point? he's a front runner, after all. you'll hear from him, just ahead. when you're not confident your company's data is secure, the possibility of a breach can quickly become the only thing you think about. that's where at&t can help. at at&t we monitor our network traffic so we can see things others can't. mitigating risks across your business. leaving you free to focus on what matters most. big day? ah, the usual. moved some new cars. hauled a bunch of steel. kept the supermarket shelves stocked. made sure everyone got their latest gadgets. what's up for the next shift? ah, nothing

. >> joining us now are casey hunt, an msnbc political correspondent, and jordan reardon.o days off, no holidays, even when you are testifying to congress. for hillary clinton and her presidential campaign, today could be a help or hurt her or could have meant nothing, so what was it? >> i think it was helpful. clintons are helpful in their enemies. so when you have obvious overreach and obvious partisan politicized hearings, and it was primetime, it really elevates hillary clinton, and it allowed her to sit there and look like a president. >> casey hunt, what is the republican reaction in washington? is it easy to find republicans to tell you why this was great for them? >> lawrence, it has been pretty difficult throughout the course of the day, which tells you more than anything what democrats will say or already are saying as a presidential performance for her, and it did elevate her as joy was saying, and i am having trouble having people who are saying this helped my guy, who is returning against hillary clinton. i wouldn't go say it's radio silence, and donald trump,

libby casey has been following the testimony, is there anything we know that we didn't know this morning when we woke up? >> no bomb shells. changes have come between jim jordan, very conservative ohighan, and secretary clinton. jim jordan circling back to the night in the attack and the immediate aftermath, there was the initial response from the obama administration citing an inflammatory video creating protests in the middle east. the obama administration said that was linked to the attack. later they changed the perspective and said the attack was self-contained by an al qaeda-like group. hillary clinton said today something she said in the past. that it was a confews fusing -- confusing time. hillary clinton brought out an email saying that two officers had been killed by an al qaeda-like group. this is at the same time the obama administration administration and the state department were talking about the inflammatory video, trying to show difference there. there has been a lot of focus and discussion on this issue of whether or not secretary clinton was disengaged in the security issues surrounding the benghazi compound. we heard one exchange by a memb

jordan who have taken in huge numbers. tens and tens of thousands of refugees. so some countries in the region have done a lot and some have not done much at all. >> senator robert caseyood to talk with you, sir. we'll see you again. >>> hillary clinton's appearance on "saturday night live" is part of a campaign to change her image? that's ahead. become the only thing you think about. that's where at&t can help. at at&t we monitor our network traffic so we can see things others can't. mitigating risks across your business. leaving you free to focus on what matters most. skwhat are you doing? the dishes are clean. i just gotta scrape the rest of the food off them. ew. dish issues? cascade platinum powers through this brownie mess better than the competition, the first time. cascade. if an electric toothbrush was going to clean better than a manual. he said sure... but don't get just any one. get one inspired by dentists. with a round brush head. go pro with oral-b. oral-b's rounded brush head cups your teeth to break up plaque, and rotates to sweep it away. and oral-b delivers a clinically proven superior clean vs. sonicare diamond clean. my mouth feel
