you should have been able to pick up on them. why should they feel they are safe and the way we vet people works? >> i think you start with the right place, chris, to try to say that people aren't uneasy, afraid, concerned is just not true. i think you have to respond to that. and certainly what happened in san bernardino, terrible thing, was it preventible? i think that's a stretch, because it's really a question of how much are we willing to give up of what makes us americans to have 100% total security? the fbi over the past summer arrested something like 60 people involved in these kinds of plots. they've got 900 investigations going on around the country in every state. they're working literally around the clock. i met with high-ranking security official yesterday. but you know, this is a problem that you can be 99% effective and there still could be something like what happened in san bernardino.
