Tough is having courage and compassion while being firm. Tough not being an insecure bully. Please don't use "tough" when relating to US police brutality.
Having a decent police force is a solved problem. Just look around for a country with a decent relationship between population and law enforcements. Look what made that happen (Was it 2-3 year police training? mental health screens? No qualified immunity? Central/federal authority governing all police forces? perrhaps ALL OF THE ABOVE?).
See how far you go with a compassionate police in Brazil.
> Crime and violence are not homogeneous around the world
It's also a bit defeatist to say that somehow the US is infested with crime and violence and that must always be the case. This isn't a problem that will be solved in just one or two generations. Attitudes take a long time to change, but perhaps Police culture is part of the propblem and not just the solution.
