No. We should eliminate the cops (who have actively contributed to the current problem as a political protest to lobby for more control) and rebuild SF law enforcement as a non-monolithic function distributed in domain-specific units throughout local government (that component of the solution is not specific to SF, but SF is more accutely problematic than most places.)
Probably less of the total manpower directed to enforcing the law should be armed with firearms, an armed paramilitary force is not a universal solution, but there still should be armed enforcement.
