I saw a few stories on the "bomblike devices" found in Boston & the crazy response. My favorite line was (from http://www.cnn.com/2007/US/02/01/boston.bombscare/index.html):
Assistant Attorney General John Grossman called the light boards "bomblike" devices and said that if they had been explosive they could have damaged infrastructure and transportation in the city.
Isn't this kind of the definition of an explosive? The damage and all? At least they weren't overreacting...
