As much as I hate terrorists, innocent until proven guilty is at the heart of our country. Even if the list were perfect, take a right away from one law-abiding group (even potential terrorists with no criminal history are presumed to be law-abiding UNTIL they break the law), which is next? Maybe those who drive HumVee's since they "pollute" and thus "terrorize" the environment?

I have a daughter. I tell her, "911 is what you dial after you're raped. 1911 is what you should have before they try."
