I'd ask myself if it's necessary. For instance I admin a community group and we make it clear that you can usually identify strangers who are suspected of or are committing crime without racially profiling them. We banned a white male because he had a bit of a fetish for racial profiling and subsequently has been shown to be a total dickhead on other FB groups - attempting to employ black women to promote rum and paying them in rum rather than the London Living wage (as is the requirement of his own fucking FB group) springs to mind.
Why do we do this? Because black men in our community have told us about some upsetting situations where they have been seen by others, merely unlocking the doors of their own homes and then been challenged/reported/photographed/shamed just because someone else reported being mugged by a black man 15 miles away.
Travellers experience the same bullshit, for instance we had a group of travellers rock up in our area last year but because no one had seen them, no comments about any crime, but as soon as they're spotted they get linked to everything and anything that goes on. My neighbour is a traveller, now settled and she said she dreaded a move because this would happen to her, then the locals would come try to poison her dogs in the night. Hell is other people.
