xkcd really hit the nail on the head today.

In a screw up so big it could only be brought to you by the government or a famous athlete, 243 guns were lost by Homeland Security agencies between 2006 and 2008. 179 guns, were lost "because officers did not properly secure them," an inspector general report said. One of the worst examples of carelessness cites a customs officer who left a firearm in an idling vehicle in the parking lot of a convenience store. The vehicle was stolen while the officer was inside. "A local law enforcement officer later recovered the firearm from a suspected gang member and drug smuggler," the report said.
