Like I said, this is a job for police officers, not machine guns. I know the events of the last few years have been unpleasant, but I honestly wish some people would stop being so melodramatic about it.
In balance, far more upset and hurt has been perpetrated by the US on foreign civillians than OBL and all the other "terrorists" put together. Can someone look at the numbers?
