I don't remember. Make sense there are some here now, but I think it's unlikely that there are thousands and thousands of Islamic terrorists coming in every year and they're sitting silently by just waiting for a signal. If they're here for an extended period, they have to work and eat and sleep and do all the other things necessary to stay alive, plus if they're terrorists, they're buying or smuggling bomb making materials and communicating and planning with one another, etc, and with our security tightening up, I think we'd be catching some of them.
Do you think we should take a head count and figure out who's in the mosques, and in turn, in those folks' homes? Shouldn't we hunt them down, and make it near impossible to get here? Would 500 suicide bombers be acceptable? How about 100? How many were involved in the Madrid bombings before the Spanish election of a Communist? 50? A couple dozen?
