mary ellen atula is joining us, a former fbi senior profiler and former fbi special agent.ng us. among the nine people, the killer in dayton, ohio, killed his own sister. what does that tell you? >> that's a pretty stunning development in that case. it could suggest that there was also a domestic violence aspect to it. as more information comes out, we'll learn that. but if you just set that aside, this is someone that came heavily armed with lots of ammunition, the vest, so the intent was maximum lethality. it was also well planned because it happened in an area where there were a lot of people and at a time of night where people may have not been on their -- have been on their guard because they had been drinking and having a good time. so he really chose the time when people were very vulnerable. so coming to an area like that shows that kind of planning, suggests that this individual has thought about this for a long time and he wanted to kill as many people as he could. >> and he could have killed more but fortunately the police got there in 30 seconds and killed him.

so i'm mary ellen carol, the executive director at the department of management. welcome. we're here to talk about the 911 which is so going to help us from a technology perspective to bring our 911 system to what we call next gen, next generation. so i've been the director here for a year, and it's just amazing how much we are able to accomplish, but with technology that is literally decades behind. we're so grateful to leadership, of our mayor and our governor, to help us to bring forward this funding that honestly is going to help us come to technology that most people in their day-to-day lives in their personal technology have above what 911 is. this is going to make our call-taking more efficient and honestly it's going to save lives, which is really the bottom line and why we're here. thank you so much and i'll hand it over to our mayor. >> mayor breed: thank you so much for being here today. i want to add to what mary ellen said about what we need to do to take our emergency response system to the next level. nowadays it's not just about making phone calls. people a

mary ellen, first of all, the suspect clearly is alive, sounds like he will will want to tell some ofthe story especially after releasing manifesto, what do you think? >> sounds like that's what he's doing and if you read closely in manifesto, the theme throughout is one quite of bit of arrogance, so it's not surprising that during the interview as he's talking to fbi agents and homicide detectives from down there that he would want to tell the story because it does seem like there's an undercurrent of arrogance and narcissism here in this individual. rob: when they say, hate crime, they are certainly investigating, obviously we will not talk too much about the manifesto that they have discussed but it was an antiimmigrant manifesto that they believe that he has written and they said they are closer and closer to factually confirming that. do you suspect this is just a very angry young man? >> i suspect that this is angry young man for a while but elevate today a level of hatred, hatred and anger are not the same thing and when one develops hatred for another group of people there's o

mary ellen, let me ask you this. when you look at motivation, you look at the manifesto, the el paso shooter echos the anti-immigrant feeling frankly stoked by the president. when you were profiling people like this, are they, in your experience, influenced by the words that they hear from their politicians, lawmakers, public figures? >> yes. i can stretch out the answer but the answer will be yes. when we do an assessment for someone that's made a threat, if that threat, whether they are known or anonymous to us, if they invoke god or invoke some person that is of a higher rank than they are, somebody that's in a position of importance, if they say these people support me doing this, that actually can make them more dangerous because they can now carry out that threat because they have the backing of god or some religious figure or somebody that's in a higher position of authority. >> you gave a direct answer there. do the president's words matter? your answer sirm yes. tom verni, mary ellen o'toole, two people with

mary ellen o'tool was on.esting and great words of wisdom from someone who did outstanding work when she was in the fbi. we use people like mary ellen o'tool to give us the best information, the best insight when we're out there and having to do things like the police are doing today and making decisions and hopefully get that information in the future out to others so that we can some day figure out how to be much more successful in preventing what happened here today. but it's a huge and complex thing to do and you're doing it at a time when other people just want to continue to use these kinds of tragedies to bring in other issues and really it really is a lot about the healing minds, mental illness and trying to identify that and help people before they do something like this. rob: terry, real quick, we don't have a lot of time, but you've got a suspect in custody. he seemed to be uninjured. now they have to find out exactly what he was thinking and why. do you think he'll be receptive to police in an inve
