For those who are interested in research-based solutions to stop police violence, here’s 12 lessons that you need to know - based on the facts and data.

Lesson 1. Everything you’ve probably heard is a lie. Specifically, the most discussed “solutions” to police violence have no evidence of effectiveness. For example, body cams don’t reduce police violence.

Lesson 2. There is no evidence that better police training programs or “implicit bias” training changes police behavior. The trainings vary in quality and rarely result in any accountability/changes in decision-making. Don’t put this at the top of your agenda. Next, what works...

Lesson 3. 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 more than 30 years of research. We identified specific policies that work here.

Lesson 4. Demilitarization. Police departments that get more military weapons from the federal government kill more people. You can stop that from happening through local and state policy. Montana (a red state) has gone the furthest on this. Your state can and should follow their lead.

Lesson 5. Police Union Contracts. Every 4-6 years your police department’s accountability system is re-negotiated. Purging misconduct records, reinstating fired officers, and department funding are all in the contract. Cities with worse contracts have higher police violence rates.

Lesson 6. Predictive policing on the police. Yes, use the technology against them. Data on use of force, complaints & lawsuits can be used to identify officers who are most likely to shoot someone next and prevent it from happening. Use the methodology to save lives.

Lesson 7. Invest in alternatives to police as crime prevention strategies. Every 10 additional organizations in a city

Reduces the murder rate by 9%

Reduces violent crime rate by 6%

Reduces property crime rate by 4%

Lesson 8. Establish non-police alternatives to 911 calls involving people with mental illness. For example, 1 in 5 of the 911 calls in Eugene, OR are diverted to mental health first responders instead of police to respond. A successful program being scaled in Portland as well.

Lesson 9. Resource the Department of Justice (after the current president is voted out) to initiate more investigations of police departments. Departments that receive federal intervention have 25-30% fewer police shootings than those that do not.

Lesson 10. Know that change is not only possible, it’s already happened in some places. Oakland police shot 8 people on avg each year 5 yrs ago and, after these interventions were implemented, they had 0 shootings this year, 1 last year (the officers were fired) and 0 the year before. Lives saved.

Lesson 11. Finally, we’ve cataloged an extensive range of research studies and other information detailing potential solutions to police violence on Campaign Zero's website.

Lesson 12. And if you don’t have time to read the research right now, we’ve presented most of this research in rapid succession in this video.

In order to establish these findings we had to:

1. Build the most comprehensive database of police violence in the US.

2. Conduct analyses of police use of force policies and union contracts in the 100 largest US cities.

3. Track every state policing bill passed in the past 5 years.

4. Track every research study published on the subject over the past five years and evaluate for quality.

5. Meticulously catalog the findings so they can be broadly accessible.

And all that with little to no funding.

Next up: We are evaluating the 1,000 largest police departments in the United States.
