What does being leftist have anything to do with anything? It's probably true most major US cities that have police brutality are run by leftists. And it's also true that more democrats own guns than republicans. Doesn't mean much. You're too enraged to see the blatant truth that the protocol on which this country operates on when recruiting members to the force is no better than a third world country's protocol. The damage has already been done, and it takes an effort from everyone to correct this nation's stupid systemic problems. Nobody is denying that all lives matter, but we as Americans need to make it clear that black lives are also included in the lives that matter.
