That's not what you said.
You said (bolding mine)
You said the voters decided thefts of under 950 are not worth prosecuting which is completely false as I showed above. The voters decided thefts of under $950 are misdemeaners that can get up to 6 months in jail and a $1,000 fine.
As for getting the clerk fired, Chasing a shoplifter was grounds for getting fired 40 years ago long before the current standard for felony theft came into existence. The reason is they value YOU more than they value a couple hundred bucks worth of stuff. Not to mention a gunfight at the OK corral in front of customers tends to drive said customers away. And that is as it should be.
Again if a DA chooses not to do his job because he thinks it's too much of a bother or because he's more interested in running to the national news network with an anti California agenda for a sound bite, that is 100% the DA's fault and not the fault of the law. And again, California's current threshold for felony theft is on par with peer states. In fact 23 states have a standard of $1,000 which is pretty much the same as California's (actually $50 more lenient a standard for the shoplifter) 16 states have an even higher (more lenient on shop lifters) number than 1,000 and as of 2020, only 9 had a lower figure than does California for felony theft. And none of those states
DAs seem to have a problem with doing their jobs.
