I think an unfortunate result of this overreaction is that concerned citizens may now want to think twice before calling anything in to the police. If you call something suspicious in, the police WILL call in the bomb squad, and shut down the city.
Of course the real blame should be on whoever in the police department decided to go all 9/11 rather than just taking a look at it and figuring out it was harmless.
At least it wasn't a Mooninite. No telling what they would have done then.
