Well he shot him once but the nut kept up the assault so I'm not surprised. Damn if I was in a situation like that I wouldn't stop until the first few clips were emptied into this fruitcake.

Heck, after emptying all my clips, i would go home, reload the ammo and shoot a few more clips just to be safe. Makes me think of vietnam where they would drug up the soldiers so bad that it took 4 shots to the head just to knock them down.
Definitely scary. while we are at it, run over the body with the car as you drive away to triple-check that double-tap.
