MI HB6119

Requires each law enforcement agency in Michigan to adopt a written duty to intervene policy within 6 months of the act's effective date.

Mandates that law enforcement officers who are present and visually observe another officer using excessive force must intervene when safe and feasible to end or prevent the use of excessive force.

Requires officers who observe excessive force to report their observations to the offending officer's immediate supervisor immediately or within 72 hours, whichever is feasible.

Establishes that policy violations are grounds for disciplinary action including dismissal, demotion, suspension, or transfer of the offending officer.

Defines "excessive force" as force beyond what is objectively reasonably necessary under the circumstances or any force that violates the U.S. Constitution, state constitution, federal or state law, or the agency's use of force policy.
