While I dispise red light runners, I dispise the cameras even more.
Fight it and verify the specs are all certified and up to date. I’ve read so many articles where the cameras have been found to be incorrectly set and the city has no idea how long they’ve been that way and basically need to recind months worth of tickets.
If the fine was a real $300, it would be a little more palletable, but in San Diego and many places, the enforcement of the cameras are outsourced to for profit businesses that get a cut.
