I think ultimately it would end up in Federal Court, and eventually SCOTUS, if an officer were convicted criminally using a different standard than Graham, et. al. California is increasingly unconcerned with Federal Law, Supreme Courts precedent, or Constitutional standards, though. Our states ruling Democrat Party is really letting their inner Confederate show lately. We already have policy in my department that explicitly states that it is more restrictive than State Law and SCOTUS case law, and includes language about "minimal force", "proportional force" and other ill advised language that would make a rational city attorney faint dead away....but here, the City Attorney is one of the Chief SJW's, so he feels no fiduciary duty to the taxpayers. On the state level, this is gonna face a firestorm of opposition....not everywhere in California is San Francisco or Berkeley. We'll see if they can gain enough support right now. My own belief is that if current trends continue, you will see a move to disarm police officers in some cities here, and it will likely be successful. No for public safety, of course....but that was never the goal.
