That's exactly how people accidentally shoot themselves or others when playing with guns.
A husband plays a pretty good trick on his wife while she is fooling with their handgun.
This is what happens when you don't take a hunter safety course. Don't ever look down the barrel of a gun you idiot.
This postal worker goes postal on an undercover cop.
Yet another idiot that does not know how to shoot a gun properly. This guy knocks out his front teeth.
His next project is to build a lightsaber.
That guy doesn't flinch with a shotgun in his face, the same can't be said about the robber after he got disarmed.
Boom, headshot! You can hear the ricocheted bullet coming back at him. Luckily it hit him in the ear protection and not the face.
Road rage goes nuclear once the guy in the car pulls out a gun.
