calling the Police is the right thing to do. But one has to be a little wary, especially if a minority is involved. Like all people, police officers don’t always do the right thing.
I remember as a young teen being with my brother-in-law (non-minority) who was driving with my dad’s camping trailer (we had just been camping) through through an extremely small town. That town is widely known as a speed trap. The brother-in law was pulled over because one of the brake lights was not functioning on the trailer (IIRC)–the vibration had loosened the connection. The officer quickly became agitated when my brother-in-law objected to something and said he would talk to his lawyer. My BIL had flown in from NYC (where he was a trader on the NY Stock Exchange) for the trip. Oh, and the cop was the younger brother of the Mayor. I thought the cop was going to get violent. He didn’t, but it seemed right on the edge, and for very little reason.
That event changed the way I thought about things. It was then I realized that one might be subject to tyranny by the police no matter WHO you are. All cops are not bad, of course. But one needs to be VERY careful. When one gets a little power and authority, as you suppose, you almost immediately start to Lord it over others. It’s a human thing. And I’ve seen it first-hand.
