You are part of the problem. Yes, YOU. If you call the police doing their job and confronting people that are doing illegal things harassment, you are just feeding into the incorrect narrative. And let's be honest, the police didn't just show up. They were CALLED. Called to come and do their job.
Don't want to be arrested or go to jail? DON'T BREAK THE LAW. Don't want to be CONTACTED by the police? DON'T BREAK THE LAW. It sounds like you are saying "oh, the black man has been through enough, so police shouldn't bother them when they do things like trespass, commit domestic assault, fight, or pay for their meals with counterfeit money. That is INSANE!
