Great subject and good ideas you brought. Here is my take on it.
Police personals must pass a questioner about moral and ethics.
They must be paid very very good.
The system as a whole must be fixed. This is what I usually say about it
if all Hollywood go on strike for 10 thousand years not much would be affected. If garbage bickers, police or fire fighters go on strike for days, federal government will declare martial law. But look at the paycheck difference. We have a lot to learn how we should evaluate /appreciate things
