The series of mistakes I listed cascade into each other inasmuch as each one in turn yanks the rug of justification out from under the next one down the line. With that in mind, I'm afraid I'm not following you on #2 and #3 - ok, my comments on #2 and #3 point out the responsibility of the army driver to comply with orders, something he repeatedly refused to do (I'm talking about the clear orders when just one cop is talking). The army guy ignored the clear order 'put your hands outside the window!' multiple times.
The cops shouldn't have made mistakes. They should have issued clear orders. But the army guy ignored orders even when they were clear.
Is non-compliance with orders a crime? Is refusing to follow along with detainment (e.g. put both hands outside the window) a crime?
The George Floyd death, the Daunte Wright death, and this stop of the army guy all show a pattern: refusal to comply with cops, which leads to escalation.
Seeing as this thread is about the crap cops have to deal with, I'll post another example.
In this video a cop stops a white woman and asks her to provide proof of ownership of her vehicle. She refuses, claiming to be a 'free inhabitant', so the cop eventually uses force to make her comply.
