Officers of the SFPD won't stop shooting citizens of the city until they suffer some penalty for killing. The D.A. must charge; the department must discipline. Shooting their guns at all should be cause for rigorous inquiry and usually discipline, even if no one is hurt. Cops will kill so long as police and political authorities don't make it certain that use of excessive force will be punished.
