The California Attorney General will begin investigating fatal police shootings, taking over those investigations from the local law enforcement agencies that had previously handled them. According to news accounts:
two newly established state teams, one based in Northern California and the other in Southern California, will have a combined 33 special agents and supervisors who can call on crime analysts, forensic experts and others as needed.
The state teams will focus solely on whether the shootings were legally justified, sending their reports to the California Department of Justice’s Special Prosecutions Section for a decision. The department will ultimately either file criminal charges or release a written report outlining why they weren't warranted
There are interesting public records implications to having such investigations occur, because the content of such investigations should (presumably) be public under the terms of SB 1421.
