That's the problem in a nutshell: once it's institutionalized there's really no way back. How many private security guards could a store afford? Enough to stop 80 armed thieves coming to clean the place out? Who know they won't be punished for doing so? And as for the citizens themselves - what exactly are they paying the government for if not for protection against the lawless?
No one is going to "crack down" once this stasis is adopted as official policy of the state. It is, as the proggies proudly proclaim, the New Normal, California Reimagined, and it's here to stay so long as they are there to stay.
