Why do vehicles get to park in red fire zones and not get a ticket?

There are lots of vehicles that are parked in red fire zones, next to the red curb and they park there for days and the cops refuse to ticket them no matter how many times they are called about it and they say it will take them three days to come out and the town is two miles across and then we see a cop drive right by the reported vehicle and and do nothing about it and we see the cops going through stops signs and they are not on a call but just driving leisurely around doing nothing. Is there a private patrol or some kind of citizen group who could do something? This is in Santa Barbara County, California but we see it everywhere.
