It's only a matter of time until the US starts getting hit with suicide bombers. For years, we thought that terrorist attacks were something that only happened in the Middle East and Europe. The first WTC bombing threw that mindset out the window. Then we thought that all terrorists were Muslim. Then came the Oklahoma City Bombing. After that we thought that the chances of another bombing was slim and none. Then we had 4 airliners hijacked and turned into flying bombs. Right now we think suicide bombers are only in other parts of the world (Iraq, Chechnya, Russia, Bali, Madrid, Beruit, Israel), and are lulled into thinking that we're safe here. Islamic terrorists and their sympathizers are going to hit soft targets (subways, malls, resturants, theatres, clubs, city streets) because of the lack of security in those places. For every potential terrorist they capture, there's no telling how many have slipped through.
