crowd sourcing crime is getting bigger and bigger. everything from atm video to video from an iphone. at a high school. is going to become critical. not only in determining who did it but determining did something happen that we can prevent in the future. it's huge. >> we talk about a terrorist being a learning enemy. they adapt the tactics. the idea a kid an 18 year-old or 19 year-old can look at other school shootings. maybe gone through training as a student in the school. and then try to figure out a way to over come and get more students out of the classroom when they're supposed to be inside. >> you're right. all you need is an imagination. if you take an 18 year-old kid such as this suspect we have in custody now, that's in custody now in broward county. he probably has been through that training. probably ever since elementary school.
