mary ellen? how much does the last guy have? >> i think the last guy has a huge effect and it e it may be three last guys before this one. but i think this copycat effect is really one of the pink elephants in the room but it's -- it's so important. is we give it lip service, but to these individuals that carry out very similar plans, they're mission oriented, they want maximum lethality, they want to stop the world and be on t.v. for a week long period of time, it's hugely important. that's part of their motivation from my experience is to have that power and that thrill seeking experience. >> rose: do we know from all those that have been studied that these are people who have a low self-esteem or a high self-esteem and don't think the world understands them which is it? >> they see themselves differently depending on the case we're talking about, columbine versus virginia tech versus the shooter yesterday. so in columbine, for example, erik harris was very arrogant and really held himself in h

. >> mary ellen o'toole, you are a former fbi special agent. a senior profiler. called in right now, to get involved and investigate. what would you be doing as a senior profiler? >> one of the first things i would want to find out mr. about the shooter's background. about the warning behaviors we know exist in these kind of cases. i would want to find out about the preparation. these cases are not impulsive. there is a lot of planning that goes night. i would be going back to look at, at the background. and how this evolved over a, probably a fairly long period of time. off awe rig >> right now we have no idea what if any mow tich ttive the may have had. >> in these cases, cases and the need for retaliation and revenge. these are thrill seeker. these are people that want ape lot of attention. he basically stopped the world right now. all the focus has been on him today. as awful as the that sounds, those are some of the motives we seen other cases. >> we also stopped himself. he its dead right now. tom fuentes. if you were involved in this investigation. i know

and in terms of the profile of this individual, mary ellen, we don't know much about the person thatspect, although we're still unclear about that. what can you tell us in terms of what you have seen in past profiles of this kind of situation? >> certainly. in prior cases what i've seen are individuals who are what i call injustice collectors, which means that when events occur in their life that they see as threatening or as insulting them, they will -- >> mary ellen, let me interrupt you, i apologize. we have to get to the press conference happening right now to get the very latest from the police chief. >> district of columbia today on the campus of the navy yard. i'm joined at this press briefing by chief kathy lanier of our metropolitan police departme department. the district director of the fbi, valerie parlave is with us as well. chief teresa chambers of the park police and the person who represents the district of columbia in the house of representatives, congresswoman eleanor holmes norton. let me, first of all, say again we all know this is a horrific tragedy, certainly on

you know those shoes are supposed to have the rhinestones, mary ellen.l 'em-- don't play with me. don't-- everybody's playin' with me. don't play with me. all right. whatever. when i snap on your ass, you're not gonna be "bye." (narrator) bernie arrives at mary ellen's for the dress inspection, and she isn't messing around. i'm just gonna inspect the dresses and make sure that they are appropriate, and they didn't change anything, and nothin's hangin' out. (narrator) once inside, bernie lines up her bridesmaids for a close inspection, and she gets personal. you gonna shave your legs, or are you wearin' stockings? i'm gonna shave my legs. okay, please do. up. you gotta shave that better. shave that better. clear-clear-clear deodorant. clear deodorant. don't come in there being all tacky. (bernie) i want you to explain to me what you were thinking when you picked those out. (bridesmaid) i thought they were cute. okay. i'll wear 'em again. cool, not to the wedding. was that your head hitting my head? see, i-i got this covered. i got it-- you just stay strai

i want to turn to former fbi profiler mary ellen o'toole. what do you make of the information so far? >> well, he continues to be a very inconsistent person. he's been described as being very sweet. he's been described as being very aguessive and when a person is described like that, you look at their aggressive side and for him going back in 2004, he didn't leak the way that these construction workers looked at him. they mocked him. they dissed him. so instead of using, you know, an appropriate response, he goes and he pulls out his glock and he shoots their tires out. it's completely disproportionate to what they did. >> that is a very critical piece of information. because that really defines an injustice collector. i don't leak what you did. >> an injustice collector. >> that means somebody that holds on to grove vanss? >> they hold on to grievances and perceive grievances when they're not there. their response to being mocked or disrespected is extremely disproportional to the original behavior, which is to pull out a gun. he does it ag

we are joined now by mary ellen o'toole. a forensic special agent.he account of that man. so many contradictions. some of the biggest this man apparently studying buddhism, a huge part of his life, yet we heard he liked violent video games and he had three arrests we know about and some involving violent, certainly firearms here. seem to be pretty big contradictions. >> i would call them inconsistencies. we all have them as human beings. but in this case, what is really very stunning is that you have him described as a quiet guy to an aggressive guy. that shift in mood, that shift in behavior suggests someone that is unpredictable and someone that is unstable. what you look at is where does that mood swing take them? that aggression with a gun is very, very significant and i think it was downplayed over the years, but that is someone who is very unpredictable. >> you're saying they seem like contradictions but it is possible for one person to live with these contradictions. you have had arrests that involve some violence while, at the same time, stud
