Why, because bad guys can be treacherous? You think your the only one who grasps that concept? What you don't seem to grasp is the rule of law, due process, rights, the existence of mental illness on the streets, statistics or actual police training.
Do you know, for example, why those cops didn't stop 50 yards away, take out rifles, scope the perp and shoot him down at a safe distance?
I'm asking you a serious question here. Do you know the answer? Because by your way of thinking, the existence of the knife and threats were an automatic death sentence. So did the cops screw up by endangering themselves with proximity and handguns, when they could have backed up in their car and used rifles?
The fact is that the vast majority of police interactions with armed and angry people do not result in killing the perp. The fact is that cops are trained in de-escalation and do it every day. The fact is that they actually have to justify firing in comparison to the option of nonviolent resolution every time they shoot. Your asinine attacks over anything less than blowing dangerous perps away has absolutely nothing whatsoever to do with police work. Killing people is supposed to be the last resort, Rambo, not the first. And discussing nonviolent alternatives is what a free people do in order to hold onto their freedom.
The police are not the military, genius. That fact doesn't make me ignorant of the realities of the street. In many ways, police work is harder than military work, because no, you CAN'T just take out the "target."
Grow the hell up.
“You think your the only one who grasps that concept?”
Yes, I do. Seems you’re not part of that set.
