Earlier quoted context omitted.
There is actually a slightly more damning view of the situation here than the moral issues around police safety. The police had complete control over how they approached this. Why then are they even in a position where they feel threatened? When we look at the outcome here, they just killed some dude for no reason. If this is acceptable to the police force; why not have them call out to the room with a megaphone? Wha…
You are reading too deep into it. The situation is that the cops have too little downside and too high an upside: since they never get convicted for these crimes, you need little to nothing to convince you that deadly force is fine. Cops need to go to jail for this. Its as simple as that. And they will find the way to not shoot like that anymore.
I'm disturbed by that line of thought. A normally educated human being from a developed country should feel bad about using deadly force, and worse after using it. The whole point of military training is to break the human instinct no to kill and even with the pressure of actual combat situation (where the upside is much higher, the downside much lower than for SWAT teams), killing breaks the soldier mentally.
What kind of people is the US is selecting (or what kind of training) for its police force that only some fear of criminal prosecution is keeping them from shooting people ?
After shooting dead an innocent, you would expect a police officer to be mentally wrecked. Even worse as he utterly failed at his primary mission of protecting the citizen which, as a Police officer, should normally be pretty high up in his list of personal priorities. So I can of understand going easy of the Police, from a legal point of view. But if the kind of people you have in the police are the one looking for the license to kill to assuage their most primal instinct, the problem is not with the legal side, you are hiring/training really wrong. That's not a police force, that's a criminal cartel.
