Investigation and Prosecution of Use of Force
At least 21 states and the District of Columbia have passed laws relating to the investigation or prosecution of use of force by law enforcement. Statutes addressing investigations and prosecution generally fall into two categories, 1) empowering an entity to conduct investigations and prosecute or 2) outlining procedurally how an investigation must be conducted.
An example of the first category, Delaware law requires the Division of Civil Rights and Public Trust to “investigate all use of deadly force incidents by law enforcement for the purpose of determining whether such use of force was justified as a matter of law.” Maine law simply states the attorney general has “exclusive responsibility for the direction and control of any criminal investigation of a law enforcement officer” who used deadly force.
Alternatively, Colorado law falls into the second category, requiring agencies to develop protocols for use of force investigations that are carried out by multi-agency teams. The protocols are required to be posted online or at least publicly accessible. Following the conclusion of an investigation that does not result in criminal prosecution, the law also requires the district attorney to publicly report findings, including the basis for the decision not to bring charges.
Many states empower the attorney general or another state attorney to investigate and prosecute crimes while some designate other government entities or utilize a grand jury process. A handful of states also empower review boards or require their participation in the investigation process.
For example, the District of Columbia’s law requires the Police Complaints Board to review all use of force incidents, serious physical injury incidents and any in-custody deaths. The law enforcement officer independent review board created by Hawaii law is tasked with reviewing investigations and making recommendations to the prosecuting attorney in the county in which the incident occurred.
Missouri, on the other hand, empowers cities and counties to establish their own civilian review boards with the authority to conduct investigations into allegation of misconduct by local law enforcement towards members of the public. All three states authorize or require civilian membership on each review board.
Most of the empowered agencies have subpoena power and the power to prosecute. Some states stop short of the power to prosecute but allow the empowered entity to discipline or make recommendations.
Law enforcement use-of-force investigation laws are not always criminal in nature, though many are. New York, for example addresses criminal consequences for inappropriate use of force by law enforcement. While Arizona statute creates procedural rules for administrative investigations. Iowa has a provision allowing for recommendation of revocation or suspension of an officer’s certification by the law enforcement academy council if the attorney general determines there is misconduct, but criminal charges are not appropriate.
The wide variety of statutory approaches to regulating the investigatory process after a use-of-force incident can be explored further in the database.
