From Samuel Sinyangwe, a thread about solutions to stop police violence:
More restrictive state and local policies governing police use of force are associated with significantly lower rates of police shootings/killings by police. This is backed by 30+ years of research.
Demilitarization. Police depts that get more military weapons from the federal govt kill more people. You can stop that from happening through local and state policy. Montana (Red state) has gone the furthest on this.
Police Union Contracts. Every 4-6 years your police dept’s accountability system is re-negotiated. Purging misconduct records, reinstating fired officers, dept funding- it’s in the contract. Cities with worse contracts have higher police violence rates.
