About This Scorecard

This is the first nationwide evaluation of policing in the United States. It was built using data from state and federal databases, public records requests to local police departments, and media reports. While police data is never perfect, and there are additional indicators that still need to be tracked, the Police Scorecard is designed to provide insight into many important issues in policing.


Police Scorecard is an independent 501(c)(3) organization, learn more about our team here. If you have feedback, questions about the project, or need support with an advocacy campaign, contact our Founder, Samuel Sinyangwe.

Use this Scorecard to identify issues within police departments that require the most urgent interventions and hold officials accountable for implementing solutions. For example, cities with higher rates of low level arrests could benefit most from solutions that create alternatives to policing and arrest for these offenses. In cities where police make fewer arrests overall but use more force when making arrests, communities could benefit significantly from policies designed to hold police accountable for excessive force. And cities where complaints of police misconduct are rarely ruled in favor of civilians could benefit from creating an oversight structure to independently investigate these complaints.


Here's how to start pushing for change

  • Contact Your County Sheriff, share your scorecard with them and urge them to enact policies to address the issues you've identified:
    Advocacy Tip:  This state has a Police Bill of Rights law. These laws make it harder to hold police accountable. Call state legislators and tell them to repeal this law.
  • Look up your state and federal representatives below, then tell them to take action to hold police accountable in your community.
