seriously because we've seen a lone wolf gun attack in the past. >> yes. >> the idea that the fbi finds these people online and then gets into their circle of influence, i guess, and kind of leads them along. it's been very successful up until now. but they've only got to get lucky once, right? >> absolutely right. i'm not a lawyer and i'm not a law enforcement person. but thankfully, they were able to do this. this came partially because of an informant. i'm not sure that the fbi was on to this issue but i think they were informed that his intention to take it on. he's a convert to islam, by the way. in some cases, folks have looked at it closely that some of these people who do support islam do want to prove their worth to their new religion. somebody saw it wanting to do harm to u.s. employees and let the fbi know about it. that's important.
