It fired.

ARLNow.com first reported the gun was in an active duty service member's car in the cemetery's parking lot before it fired*. He was trying to move the gun from under the seat when it fell to the ground, injuring a passenger in the leg, Sharon Walker, spokeswoman for Joint Base Myer-Henderson Hall, told CBSNews.com. Weapons are banned at the cemetery.

I'm pretty sure there was a finger involved there somehow.
