SEATTLE (AP) — The state Senate has approved a measure requiring police to intervene if they see a fellow officer using excessive force.

The bill, sponsored by Redmond Democrat Manka Dhingra, passed 28-21 Tuesday over opposition from Republicans. It’s one of many police reform bills being considered during this legislative session.

Under the bill, officers would have to intervene to stop excessive force if they see it being used by another officer and they’re in a position to do so. It would also require police to report wrongdoing by another officer to that officer’s supervisor, and it would forbid retaliation against police who intervene or report wrongdoing.
