I get your argument, believe me I don't feel sorry for the person that was killed by these cops. They should have listened, dropped the weapon as instructed and this wouldn't have happened. What I don't agree with is that every situation is going to vary. You're talking about making split second decisions, but in this case specifically, they had all the time in the world to assess the best course of action. My argument is that with BETTER police training, they would be able to assess situations like these better. Do you feel the police handled this the most optimal way?
I get the whole darwin argument as well, i'm on board. we don't really need these retards procreating lol, world is better without them blah blah. I've just seen so many situations (not just this one) being handled in an non-optimal fashion, where i strongly believe better training could have prevented some casualties, using more logic and less heat of the moment reaction /emotion.
Based on what I've seen in the video, it's hard to argue that they didn't do things optimally. They ordered her several times to drop the weapon. The female cop backs away off screen, the male cop backs away and puts the barrier gate between himself and the suspect while repeating the orders. She doesn't drop the weapon, and then proceeds to advance on the offscreen cop, faster than she had been moving during the entire encounter up to that point.
The problem with the "optimal" argument is acting like it's readily obvious from the POV of the officers, and rarely if ever takes into account the officer's well being. "Well why didn't you properly diagnose a cry for help instead of a mental break? Why didn't you risk getting stabbed to make sure that person wasn't really trying to harm anyone? Etc."
