Terrorism & Extremism

The [Trump administration's] proposals don't call for constant monitoring once someone is in the country. It seems like [Saipov, the NYC attacker] became much more radical relatively recently. So the ideas on the table don't seem particularly relevant to this attack.

This is a movement that historically has been highly divided. One thing Osama had been doing is trying to be a unifier. He was very comfortable working with people who agreed with him on one issue and disagreed with him on five. Toward the end of his life, a lot of what he was trying to do was to get groups to work together.

The challenge for do-it-yourself terrorism is pretty significant. They download the app, they might click on a hashtag and then they're one or two more taps away from connecting to someone who could point them in a violent direction.
