Well, when they are in a "red suitcase hidden in the rear of a park where both pro-government and anti-war rallies are regularly held," they are! Rockland police blew up the suitcase, found in Nanuet, because, the Journal News reports an X-ray "revealed three cylindrical canisters and something that looked like tools and wires." But it turned out to be two cans of tuna fish and one can of corn—the tools were pliers and a manual can opener. A police officer said, "More than likely, some homeless guy lost his dinner." Better safe than sorry, right?
