"This isn't the way counterterrorism is supposed to work, but it's happening everywhere"
From Bruce Schneier's The War on the Unexpected:
“This story has been repeated endlessly, both in the U.S. and in other countries. Someone -- these are all real -- notices a funny smell, or some white powder, or two people passing an envelope, or a dark-skinned man leaving boxes at the curb, or a cell phone in an airplane seat; the police cordon off the area, make arrests, and/or evacuate airplanes; and in the end the cause of the alarm is revealed as a pot of Thai chili sauce, or flour, or a utility bill, or an English professor recycling, or a cell phone in an airplane seat.
Of course, by then it's too late for the authorities to admit that they made a mistake and overreacted, that a sane voice of reason at some level should have prevailed. What follows is the parade of police and elected officials praising each other for doing a great job, and prosecuting the poor victim -- the person who was different in the first place -- for having the temerity to try to trick them.
I would elevate this to most important:
“Equally important, politicians need to stop praising and promoting the officers who get it wrong. And everyone needs to stop castigating, and prosecuting, the victims just because they embarrassed the police by their innocence.
