Congressional Oversight of Unjust Policing Act This bill establishes the U.S. Commission on Unjust Policing to investigate law enforcement activities and decisions related to the security breach at the U.S. Capitol on January 6, 2021. Specifically, the commission must investigate decisions made by leadership of the U.S. Capitol Police (USCP), the Federal Bureau of Investigation, the U.S. Secret Service, and the Department of Homeland Security leading up to and during the siege at the Capitol, including an assessment of whether conscious and unconscious bias was a factor in the miscalculation of the risk posed by protesters to Members of Congress and their staff. The commission must also investigate whether current USCP officers have ties to white supremacist and other extremist groups, movements, and organizing efforts, and whether any USCP officers neglected their duty and colluded with protestors or other law enforcement entities. Further, the commission must recommend specific measures and reforms related to realigning (1) USCP priorities and practice to address disparate use of force and surveillance targets in and around the Capitol; and (2) USCP recruitment, hiring, and retention policies and practices to address conscious and unconscious biases.
