approach this holiday. ashleigh? >> rene marsh live in the nation's capital. thank you for that. i want to bring in cnn's counterterrorism analyst and former cia counterterrorism official phil mudd. phil, what aren't we seeing? we're seeing what they're seeing, the physical, the people with guns, the extra special patrols. what areren't we seeing? >> you've got threat briefings everyday in the life i used to live in the fbi. you're looking at triage cases if you think of a hospital. what are the most serious cases? and when you've got a holiday like this coming up you have to ask yourself a question. if we're looking at cases, for example, where someone appears to be radicalized, conversations on facebook, for example, do you intervene early in an effort to prevent something you can't see happening on july 4. >> so maybe detentions could be happening today of people suspect up until now and they don't want to give it the chance for tomorrow? >> you might go talk to them and say "hey, we've been looking out for you. i don't expect to see anything happen." remember, there's another piece of this.
