Understand how law enforcement fits into a larger legal system with courts and individual rights.
Police are only one part of the justice system. Legislatures create laws, executive agencies enforce many laws, prosecutors decide what charges to pursue, courts interpret and apply law, and constitutions and legal rules protect individual rights.
Police enforce laws created by legislatures and governments within their legal authority.
Learn MoreA warrant is a court order that can authorize certain searches, seizures, or arrests.

Learn MoreThe U.S. Constitution and state constitutions place limits on government actions.
Learn MoreCourts determine legal questions and decide criminal cases through established procedures.
Learn MoreLaw enforcement agencies can be reviewed through courts, internal systems, elected officials, civilian oversight, and public records laws.
Learn MoreOfficers do not personally create criminal laws. Federal, state, and local governments pass laws and ordinances, and courts interpret how those laws apply. Agencies also have policies that guide how officers perform their duties.
Many warrants are issued by judges after reviewing information presented under legal standards. The exact rules depend on the type of warrant and jurisdiction. Some situations allow action without a warrant under established legal exceptions.
Due process can include notice of charges, legal hearings, access to counsel in certain cases, rules of evidence, and review by courts. These protections are important because government power is limited by law.
Rights related to searches, self-incrimination, legal counsel, due process, speech, and other areas can affect police work. Courts decide how constitutional rules apply to specific situations.
Police investigate and make arrests in some cases, but courts decide guilt or innocence. Judges manage legal proceedings, and juries decide facts in many trials. Prosecutors and defense attorneys have separate roles.
Accountability systems differ by location. Complaints may be investigated internally or externally, courts can suppress evidence obtained unlawfully, governments can change policies, and some jurisdictions use civilian review boards or inspectors.
