I agree that this is very sad. I think < my opinion> that unfortunately, especially historically, certain institutions and practices <institutional racism for example> have had such power, that even the police don't do anything, or do less than what they should. Other things like - spousal abuse, for example - in an example, as in many cases still - the female partner calls/gets cops to come - but historically, no one is arrested because the couple is married, the abuse happened in their home. "not our business" the cops say.
