I don't think this is evidence of that at all. I think the general public has noticed abuses of minorities over the past several years and is appropriately outraged. The primary change I can see is the ubiquity of cameras. Their emergence and widespread popularity after the turn of the century has brought accountability to the most corrupt and dishonest among the police force. Everyone seems to be outraged at the abuses, whether the victim is minority or not. Unfortunately I think that minorities have suffered much more significantly under the boot of these corrupt authority figures.
