Pattern and practice investigations
In 1994, Congress authorized the U.S Department of Justice (DOJ) to investigate and litigate cases involving “a pattern or practice of conduct by law enforcement officers” that violates Constitutional or federal rights.
- A few states have state statutes permitting state Attorney General to perform state-law investigations of police departments.
- Minnesota does not have a similar law.
- However, the Minnesota Department of Human Rights (MDHR) has the authority to investigate under the Minnesota Human Rights Act.
