End Racial and Religious Profiling Act of 2021 or ERRPA This bill establishes a framework to eliminate racial profiling at the federal, state, and local levels. Specifically, it requires federal law enforcement agencies to maintain policies and procedures to eliminate racial profiling, including training, data collection, and complaint procedures. State, local, and tribal law enforcement agencies must maintain similar policies and procedures as a condition of receiving funds under the Edward Byrne Memorial Justice Assistance Grant program and the Community Oriented Policing Services program. To enforce violations, the bill authorizes civil suits by the Department of Justice and affected individuals.
