Who Enforces The Enforcers?

There was supposed to be rain today but being Earth Day, I put away my lazy/don’t wanna get wet excuses and got on my bike for the ride to work. As I discovered on the way in it must have also been Block The Bike Lane Day as demonstrated by a variety of motorists, including the most ironic one (pictured in sequence  of my approach/arrival below): a Department of Transportation Parking Enforcement officer sitting in her vehicle that she has parked in full obstruction of the bike lane on Venice Boulevard while issuing a citation to the vehicle parked at the curb — despite there being ample curb space in front of the violating vehicle for the officer to park and thereby avoid me yelling at her not to block the bike lane as I passed (click for the bigger pictures).
