Pentagon looking at gunfire detection system

Friday - 10/22/2010, 1:15am EDT

"Shot spotter" is being considered for use at the Pentagon specifically to help in situations like the one that unfolded yesterday. "Two exterior windows had been hit by gunfire," says Pentagon Force Protection director Steven Calvery. Shot spotter is a gunfire location and detection tool that uses acoustic sensors to determine where gunshots came from, when they were fired and it can even determine whether an automatic weapon was used.
