MI SB1093

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

Mandates law enforcement officers who visually observe another officer using excessive force to intervene when safe and feasible to end or prevent the excessive force.

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

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

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