Seems to me that cops pretty much have impunity these days.
A guy waves a machette around and the only way to stop him is to shoot him dead?
Pepper spray didn't work?
The taser didn't work?
Shooting him in the leg didn't work?
Hey, maybe just talking to the guy would have worked. Who knows? Did they try to talk to the guy?
Apparently none of these options were even considered.
But a bullet in the chest stopped him cold.
A bullet in the chest will do that.
