Having a tail light out while being a black man shouldn't give the cops the right to assume he is likely a violent perpetrator. I mean seriously how often has a man been pulled over for a traffic violation ONLY, and ended up murdering the cop? Let alone after calmly and politely telling the officer he had a legal firearm and with his family in the car. Cops have plenty of respectable interactions in similar situations, without being the agitator, aggressor, and unloading seven rounds into another human. The cop had zero reason to be afraid for his life, so non premeditated murder that isn't self-defense = manslaughter.
