On the one hand LA county has a massive crime issue and the masks aren’t helping. On the other hand, even without masks they still had a crime problem anyway because LASD (almost $4bn budget) sucks at their jobs and there isn’t a lot of support of the current Sherrif from deputies that has been trying to fix them. LAPD ($2bn budget) basically only takes care of the main part of LA city proper itself.
