Police misconduct means the improper actions taken by police officers in relation with their official duties. Police misconduct often results in miscarriage of justice and discrimination. Police misconduct includes deliberately obtaining false confessions; false arrest; creation and use of falsified evidence, including false testimony; false imprisonment; intimidation; police brutality; police corruption; political repression; racial profiling; sexual abuse; and surveillance abuse. Police drug use is also an emerging form of police misconduct. In the U.S., police misconduct is controlled by the exclusionary rule which says that evidence gathered through misconduct is sometimes inadmissible in court.
