How about a few common sense suggestions to help defuse riots

*   I find it hard to believe that it is procedurally risky to arrest the other 3 police officers who watched their buddy knee the life out of George Floyd for some charge immediately.  Can't the charges be later modified if needed?   Civil order across the entire nation requires people being able to see justice at least being started promptly - especially when everyone knows what happened from their TV. 

*  How much freaking common sense does it take for heads of police, governors (or even the President himself) to come out and say that restraint methods involving interference with air or blood flow through the neck are banned - never to be used?   That all police forces will ensure that all restraint instruction will emphasise the need to not do things obviously dangerous to the life of the arrested?

*  How much common sense does it take for heads of police or governors (or even the President himself) to come out and say that police who hide their identifying badge numbers are committing at least an administrative offence and will be punished for seeking to protect any of their own unjustified violence?   The riots are about lack of confidence in the police - they need to show why they can be trusted, and hiding identity shows they can't be.   And what about the convenient turning off of body cams?  Some places are acting:

Louisville Mayor Greg Fischer fired the city's chief of police Steve Conrad after it was discovered that police officers had not activated their body cameras during the shooting of David McAtee, a local black business owner who was killed during protests early Monday morning.

Why it matters: Mandatory body camera policies have proven to be important in efforts to hold police officers accountable for excessive force against civilians and other misconduct. Those policies are under even greater scrutiny as the nation has erupted in protest over the killing of black people at the hands of police.

but again, I say there needs to be serious, immediate action against all police who deliberately turn off their body cam.
