People say "there should be a law against it". Well, politicians pass a law against it. And then arrange things in a way that makes the law useless since police unions' support brings in sweet money and votes. And then frame the discussion about police misconduct in a way that you either ok with anything and everything the police does, or you support abolishing the police altogether and violent mobs trashing your town daily for sports. That is good for brining in votes too. So I guess that's the point for them. What's the point for people to tolerate such system? Please tell me if you ever find out.
