I think part of the problem is LEO are a little too good at killing people. Maybe cops would benefit more from some soft skills training.
It is hard to get the balance right between being able to clamp a guy with a degree of safety and not going overboard.
And it is hard to get right.
A lot of killings seem to be a lot of little errors that lead to big errors.
So say you go to a job on your own. Because that is more cost efficient. That is a small error.
So you get out and you put yourself somewhere a bit unsafe. Small error.
You mess up your instructions, or don't communicate as well as you could. Small error.
Then you get in to a fight that you didn't think would happen. Small error.
You then do something dumb in that fight. Small error.
Then you have to dig your way out in a blind panic. Person dies.
Now If some of those errors get fixed the likelihood of a guy getting killed reduces.
So there was this cop in Australia who got saved by some tradies. So he misjudged the guy but was dug out of his situation by a couple of other guys.
Sorry I am trying to explain this in a way that is not so disjointed and kind of failing here.
