Law enforcement: training; duty to intervene policy; require law enforcement agencies to adopt. Creates new act.

This bill requires Michigan law enforcement agencies to create written policies mandating that officers intervene when they witness another officer using excessive force. The legislation defines excessive force as any action beyond what is objectively reasonable to protect safety or comply with laws, and it obligates officers to stop such incidents whenever it is safe and feasible to do so. Additionally, the bill mandates that officers who observe excessive force must report the incident to a supervisor within 72 hours, and it establishes that failing to intervene or report is grounds for disciplinary action, which can include dismissal or demotion. Agencies are also required to provide copies of these new policies to all their officers, while retaining the ability to adopt stricter rules if they choose.
