It's unfortunate, certainly, but it's probably very useful for police to have knowledge of and experience with the communities they're policing. In Canada police officers who are expected to work with indigenous communities often get special training to familiarize them with those cultures.
Sure, you (presumably) want the police to be sensitive to cultural issues -- the problem is you can't use skin color as an indicator of inclusion in a cultural group.
I was watching an interview the other day from one of the Tuskegee Airmen and just going by his physical appearance he looked as "European" as I do.
