I, too, want to see an end to racially motivated police violence. I, too, am frightened by the trend toward militarization in the nation's police forces. Something must be done, and it must be done right now.

I have a difficult time imagining what a 'police-free' society would look like, though. How would we deal with crime? It's true, the police are frequently more criminal than the suspects they pursue, but I nevertheless wonder what a legitimate and effective alternative might be.

Can you describe what we might replace police departments with?
