I'm not black but I've been subjected to stop and search on the streets of London. I've been taken aside and put in a room by police while they checked me out on entering the UK only to eventually be told "OK, you can go" at the end of it, no apology. But generally I've found with police that if you're polite and cooperative they are respectful in return. My first boss in the UK, who wasn't white, one of the first things he said to me was to be wary of black people, they have a chip on their shoulder. I was pretty shocked to hear him say that actually.
