Training Exercise Standards Change after Mock Grenades Left at Airport

Officials at San Francisco International Airport have said that the rules for law enforcement exercises will be tightened after firefighters left behind three mock grenades and a replica handgun during a recent training exercise.

The simulated weapons were found by a janitor on Wednesday (19 January) on the floor of a locked room in Terminal 2, which has been closed to the public since the new international terminal opened in late 2000, and which has been used as a training ground for various law enforcement agencies. There was no security risk posed by the simulated weapons, said an airport spokesperson.
