It is better that ten innocent persons suffer than that one guilty escape.
-- Bizzaro William BlackstoneStill, I would hope that as police are investigated they are held to a high standard of behavior. They do after all have a near monopoly on the lawful use of violence.
If there weren't riots, the topic would be whether to charge the direct murderer. Because of the riots, the discussion has shifted to charging his accomplices. This is progress, but not enough progress.
And yes, I definitely want to see them convicted. If there was a video of me preventing an EMT from checking a man's pulse while my co-worker choked him to death for 8 minutes, the last 3 of which the victim was unresponsive for, I wholeheartedly believe I would be convicted of being an accessory to murder. I want the same for these cops. This isn't a grey area where the person could reasonably be innocent, we have the video of an unresponsive man being executed in broad daylight.
Uhm... when the 3rd precinct got burned down and George Floyd's murderer faced charges the next day? Cops don't normally face charges for murdering black men in broad daylight, so I don't take the timing of arson and charges as coincidence.
Of a cop murdering a black man in broad daylight and not getting charged for it? Hell, here's an example I just pulled up for someone else of a 12 year old black kid being murdered while he played airsoft in the park[0], the cop faced no charges and was subsequently hired by another police department in the same state. It's like paedophile priests getting shuffled around by the Catholics, absolutely absurd.
You want another example of riots leading to change? The Civil Rights Act of 1968 was signed into law during a storm of riots that had broken out following the assassination of MLK.
