Blood spatter does not automatically equal a fatal wound. He also could have applied a tourniquet to it if it was in his arm or leg.
And the longer the siege wore on, the greater the chance he could get one last shot off at an officer who was exposed for a moment.
I have no problem with the tactic of burning this creep out. He had killed enough already.
True that.
Even the toughest of us will feel significantly more motivated to surrender and get medical care after a couple hours of trying to deal with such a wound on our own. No anesthetics, no antibiotics, the bleeding that won't quite stop, that strong odor of blood and damaged tissue, with is that a little hint of gangrene, maybe?
