Having your own little private universe of beliefs that can't be falsified is pretty dumb. There is a city dashboard that shows the disposition of cases presented to the SF DA and the rates of various outcomes have been basically flat for decades. The thing that has changed is the cops have figured out they will still get paid even if they do nothing, or don't even show up. In the decade from 2012 to 2022 the number of cases the SFPD presented fell by half. This has nothing to do with the rate at which the DA brought charges.
