Brian, you clearly don’t understand the kind of stress a cop has to deal with in a situation like this. This “kid” was no innocent waif. He already showed a propensity to commit crimes and do whatever he wanted, irrespective of the law or what a police officer was instructing him to do. He willfully got into a physical altercation with a cop…and the “kid” is HUGE and violent. The cop does NOT know whether or not a suspect is armed in a situation like this. There is the possibility that he had the right to use deadly force.
We need to find out what happens in the investigation so that we can (hopefully) get a full and complete understanding of what happened.
And as much as you’re likely to say that the cops will have each other’s backs, the thugs will do so as well. And many thugs will intimidate witnesses who attempt to give their perspective if it can be used against the thugs.
