You know, even as we figure out more about what happened, we need to get to work. And I have a number of proposals how to tackle this issue of self radicalization. I would set up a team exclusively dedicated to detecting and preventing lone wolf attacks. And that means providing more resources, creating more integrated intelligence use among all levels of law enforcement, strengthening the communication that we have coming from abroad, as well as internally, and working with Silicon Valley to prevent online radicalization. This killer was interviewed by the FBI three times and I'm not going to second guess what career law enforcement professionals do everyday to defend our nation. But we need to look carefully at this. Should we have a broader database? You know, someone comes to the attention of FBI not once but three times, does that suggest that local law enforcement needs to know. That people need to be more aware? Do we need to, you know, push the Congress harder to pass a law forbidding anybody on the no fly list from buying a weapon in our country? Something they have refused to do. And should people who express the kind of admiration and allegiance to terrorism be on that list? So I think we're going to have to take a hard look about what more we can do to prevent this kind of lone wolf attack.
