This is a step in the right direction. I'm disappointed it did not get more specific with police tactics but it's still good. California’s new law to stop police shootings, explained The legislation also means that after a deadly shooting, the actions of police officers that led up to the violent encounter will be considered in the decision of whether or not the shooting was in fact “necessary.” Bibring told me that under AB 392, “the decision makers — juries, police captains, prosecutors — have to look at the officer’s conduct leading up to the shooting. That means they can consider whether an officer failed to use deescalation tactics or escalated the situation,” leading to a violent encounter.
How nice that the courts now take into account what the cops actually do when they shoot someone. That's progressive for the US.
