Eric Garner was not committing a crime. He was murdered by the police for no reason. (Eric Garner was illegally selling cigarettes, certainly not a justifiable reason for his death, but a crime nonetheless. No crime, no contact)
Philando Castile was not committing a crime. He was shot to death for supposedly reaching for a gun. (Castile was armed. Why was he stopped? He allegedly matched the description of a robbery suspect. He was carrying legally and tried to do the right thing, the rest of the stop was a clusterfuck that ended with the officer (imo) overreacting, which may or may not have anything to do with Castle's race. I saw a video just the other day of an officer shooting into a vehicle and killing a white man who was armed and not following commands no protests, no fires, no one shooting at cops.)
Oscar Grant was not committing a crime. He was shot to death by the police for no reason. (Oscar Grant? I got nothing, that was an f'n disaster.)
This list goes on. And on. And on. Hell, Michael Bennett of the Seahawks was trying to get away from a shooting and was attacked by the police. He had committed no crime. (Michael Bennett is no saint. LV poilice were responding to a call of shots fired: "As they moved toward the nightclub, an individual later identified as Bennett was seen crouched down behind a gaming machine as the officers approached," McMahill sald. "Once Bennett was in the officer's view, he quickly ran out the south doors, jumped over a wall onto Flamingo Road East of Las Vegas Boulevard into traffic." *Act like criminal, get treated like a criminal. I'm sure any person of any skin color would've been treated the same way.)
The premise of your entire thesis here is entirely, demonstrably, false. (I disagree. If Eric Garner was't illegally selling cigarettes, he may be alive today. If Michael Brown hadn't committed that robbery, he may be alive today.)
