The JCPA vehicle is the most glaring, but frequently cars with FOP plates also park in front of the fire hydrant. I have witnessed the street sweeper go around it on street sweeping days and the car is not ever ticketed. Every time I see something like this, I take a picture.

A JC Parking Authority vehicle regularly parks illegally on our street - either in front of a fire hydrant or on top of the crosswalk. But of course they can do it since they are the Parking Authority and they are clearly playing by a different set of rules.
