Strict hiring policies so you aren’t scraping the bottom of the barrel. Better and longer training pipelines so you’re getting career professionals instead of thugs. Better accountability and enforcement of regulations so they’re being held to standards consummate with their responsibilities. Letting beat cops police their own communities so they have a stake in things.

And this I think is unique to the US, getting rid of the mind boggling layers of law enforcement. In Australia, we have state and federal police. Not state, federal, county, city, campus, sherrifs, and whatever.
