been to say, well, it's okay if you don't. >> is this rhetoric dangerous? do you see a connection in danger here? >> i do. in my world i used to go back. i started in world counterterrorism a long distance from what we're dealing with today. as i saw evolve from the poor al qaeda people, and there is a connection here to what we we saw with isis, validation. someone looking at a message they saw on tv and saying i'm angry. i'm angry at the military, at a government building. and these people speaking with heated rhetoric, give me validation to go do something to act on my anger. >> it is easier to find that validation online. that is also a major part of it. it is so easy to find even the one person who agrees with you
