@BillRM,
I see you are blaming everyone in one organization for the actions of a few but exonerating everyone in another organization from the actions of a few.
By the way the head of the police union defended the more than one officer that talked about how to run over protesters and get away with it. Not only that, but MOST police officers didn't denounce the statements so by your reasoning they all lost credibility, didn't they?
Or is it only people with black skin you apply your reasoning to while it doesn't apply to those with blue uniforms.
