My solution-
1) SPend more money on addressing the core causes of crime - poverty, mental health, addiction, and gun proliferation.
2) Pass some common sense gun laws that make it a lot harder for criminals to get guns, and hold gun makers accountable when they do.
3) One liberals won't like, bring back mental hospitals for the clinically insane.
4) Invest heavily in drug rehabilitation centers.
5) Ensure that more police are from the communities they patrol.
6) Get rid of qualified immunity protecting the bad apples from liability.
7) Get rid of police unions protecting the bad apples
