After watching the video again I stand by the description. At that position in the video the man faces them and has his knife arm fully extended before the shots are fired. There is a second perspective following the first that shows this more clearly.

Given he yells "you're going to have to fucking kill me" seconds prior to being shot it's hard to interpret any of that as a surrender.

The other controversial killing in recent memory is a non compliant armed man. The body cam footage is inconclusive on this one to me. The man certainly doesn't seem like a threat because he's on the ground. However, he was struggling and armed with a pistol. They gave him many opportunities to surrender.

I just stepped through it again, and you're spinning like crazy. He doesn't extend that knife. He doesn't face the police until after he takes a bullet in his side. He never got within knife range. He never approached the police.

He did not have to be killed. You're really telling me that we can't ask for three more seconds to let him drop the knife or actually approach an officer with it?

And that's the problem with this logic. You want to allow absolute hair trigger aggression by police officers. And when you allow that, you get innocent people killed. Because the cops can't make that decision correctly every time, and if you train them to shoot first, they will.

This guy didn't have to die. I don't know what was in his head, but I know he didn't have to die.

There's a 21-feet distance supposedly required for a trained shooter to draw and fire a gun before a knife attacker can close in. Sure, they had guns drawn, but you still cannot "wait" until they approach.

And, frankly, this "didn't need to die" perspective is alien to me, and I bet most people. If it was my life on the line, I wouldn't even allow a 1% increase in risk - the guy readying to, and obviously willing to, attack someone with a knife deserves to die. Does he "need" to die? No. Maybe event if he's literally in the process of stabbing someone, it would be wonderful if we could freeze time and just take him to a mental ward. But is it acceptable for him to be killed? Without a shred of doubt, yes.

But.... they were pursuing him! They chose the distance! If they weren't able to safely stop him because they were too close and had to kill him if he stopped (because let's be honest here: they killed the guy because he stopped)...

Isn't that STILL a failure of policing? It's it STILL true that he didn't need to die? Why were the cops' "lives on the line" if they were the ones choosing to engage?

They were not the ones initially choosing to engage. I wouldn't expect them to have sound judgment or impartiality after they were attacked in the first place and fired at with a taser. Again, he absolutely didn't need to die, but he totally deserved it and the cops' reaction is understandable. If I ever attack a cop, wrestle his taser off of him, and fire at him as I run away, I'd like to, in advance, absolve the cop of all responsibility of shooting me in the back. I understand he wouldn't quote need unquote to do it, but it is totally acceptable if he does.

You don't have to be within "arms range" of a police officer for them to shoot you if you have a knife. It's generally accepted that someone with a knife is a deadly threat at about 20 feet or so away, as it takes a little over a second for them to cross that distance. In that video, the man who was shot clearly drew a large knife and turned towards the officers before they started firing.
