    Performance Metrics to Improve Police-Community Relations

    Feb 23, 2015

    Changing the way police performance is measured could prevent issues leading to civil rights violations and poor police-community relations. Should California take the lead to recommend that local law enforcement agencies must report performance metrics?

    Assessing the Value of Mounted Police Units in the UK

    Nov 19, 2014

    Research in the UK shows demonstrable and measurable value of mounted police in various deployment scenarios, but the decision to maintain, expand or cut mounted capacity must be based on the priorities a police force sets within limited and contracting budgets.

    When It Comes to Police-Community Relations, “Expect What You Inspect”

    As the President's Task Force on 21st Century Policing report suggests, local governments should evaluate police on more than crime statistics, and police departments and officers should be held publicly accountable for meeting the community's expectations. Adding new dimensions of performance metrics would help.

    What Research Says About Profiling

    When police take action on the basis of race, creed, or ethnicity it is corrosive, unfair, ineffective, and can stoke the flames of police-community tension. But as we have found from a variety of assessments, law enforcement is best served when it bases its activities on risk—not on personal characteristics.

    Prior Removal and Recidivism

    President Obama's executive action on immigration includes a new program that targets immigration enforcement at those arrested for more serious offenses and those deemed to be risks to national security. Research shows that unauthorized immigrants who have been previously deported are more likely to be rearrested after jail release, so local public safety interests and federal immigration enforcement priorities may well align around immigrants with a record of prior removal.

    Assessing the Value of Mounted Police Units in the UK

    Mounted police have been part of British policing for the better part of two centuries but little was known about their work from an academic or practitioner standpoint. RAND Europe helped to investigate both quantitative and qualitative indicators relating to the value of mounted police in various deployment scenarios, in an effort to understand how members of the public perceive and respond to mounted police deployments.
