Haha, that's a fine judgement of probability! Though, it's not the probability, it's the pertinence.
Thanks and yes I know, just trying to be as witty as you
People don't want to be shot when they are doing everything the police tell them to.
If the police think that this is acceptable, then the initiative for correcting this state of affairs must come from outside the police force. By political action.
The different variations of "the people are just asking to not be shot everytime they go out!" is like the best meme of all time regarding the US police - public FUBAR relationship today and shows the retardness of anti-police movement
Police is one of the toughest, most demanding and codified job, especially so with the US history of public scrutiny.
Like Lt_Anders said the impact of the public on how police operates can be a two edged sword: it probably pushed the police to become way better than before but at the same time it can stop police from doing police.
From what I've seen, read, felt, the US police is almost as good as it can get under the immense and still growing pressure and hate from the people they serve, mostly blacks in the wrong neighoboroud and white liberals with a passion for unearthing injustice even where there is none.
When the "political action" you mentionned becomes harassment, obstruction and hate toward those who impose law and order (policemen), what happens is what you see today in the US: people do not respect police work, hinder their actions, resist lawful intervention and see all perps as victims of a pre-supposed wrongful police before thinking up of anything.
Add gender/race/identity/what have you, social media SJW's bubbles, and humans being the usual generalization machines, mixing up the bad and the good and proclaiming that everything is either bad or good, and you got the US police work environment today. A bigoted shitfest that is in great need of political support from the government.... not more "political action" from extremists retards (not saying you are, but you seem to be part of the misguided bunch at the very least).
It completely runs opposite of what you say but I really think the police needs to become more protected from the civilians, and not the other way around, in the US. Someone important like the US president need to step up and say "we love our police" while keeping it strictly under control (it always need to be), and start actively building government-police and police-civilian trust ASAP.
