Perhaps a new criterion for policing is obliged: police shouldn’t fire first to defend the innocent. David French writes in NationalReview.com:

There is absolutely no question that police have a difficult job. There is no question that even routine encounters and wellness checks can—on rare occasions—escalate to deadly violence. But there is also no question that time and again police have enhanced the risk to the public through their own mistakes. Poor tactics can yield terrible results, and police should not be able to use the ‘split-second decision’ defense when they created the crisis. There is no greater violation of liberty than the loss of your own life in your own home at the hands of misguided, panicky, or poorly trained agents of the state.
