If we remove the current police we have the room to reform them better. Also the FBI is less corrupt than current state level police.
Still corrupt. But less. The FBI can do it in the meantime.
But in reality we need police reform. We need to make them walk their beats again. They need to police the places they live, not neighboring counties. They should mostly not have guns. A good chunk of the force should be replaced with social workers. And qualitative immunity needs to go away permanently.
