But a lot if not most murder by police happens in cities controlled by Democrats.

So this is going to take much more than voting.

TBH I think the George Floyd/Breonna Taylor protests have achieved more in the fight against police oppression and murder than decades of 'reform' from elected politicians, of either party.

We have to vote. We also have to get out in the streets (for those that can). Or do mass actions such as what the NBA players are doing right now.
