Significantly expanding police training, and greater coverage of topics such as nonviolent de-escalation, community outreach, implicit bias training, and how to work with mentally ill individuals. Greater accountability through body cam programs, and community oversight boards for police departments everywhere. De-militarization of police, because right now, the police can legally buy surplus military gear and use it on American citizens, up to and including tanks. Frankly, I'd like to see most beat cops completely disarmed (but that seems unlikely to happen soon). I'd also like to see yearly community service requirements for police; make them volunteer their time in the communities they patrol, so they can feel invested in it and get to know the people there.
