Something on the order of 30,000 to 40,000 Americans die in car crashes every year. Depending how you count (lung issues etc... ) 3000 to 10000 people died in 9/11.

I think Escherize's point was how silly it is we don't worry about car crashes which are a real and countable, and yet we worry about third world script kiddies which likely have none of the effectiveness of the 9/11 hijackers.

Terrorism in a typical year in the United States kills fewer people than bathing, smoking while sleeping or basketball. We should do what it takes to maintain a comparable level of safety to this and not get caught up in useless scaremongering.
