from people coming from outside. not since 9/11 has there been a major attack from people coming in from outside. that piece of the puzzle has been taken care of. as you know, the amount of vetting into the united states by any people from syria or iraq or the refugees or any of those coming in is humungous. it takes up to two years of multiple vetting by the relevant u.s. and u.n. and other agencies, including agencies in jordan and all the rest of it, to vet people who just want to come in for asylum reasons. that is something the u.s. does incredibly well and exhaustivly. people in law enforcement are concerned that the ideas muddy the waters when you are actually trying to get to the heart of the matter and try to figure out how to stop the home grown stuff. that is the crisis that we're facing right now.
