This looks like gang graffiti.
It showed up over the weekend, late Saturday, early Sunday. It is on the perimeter fence of what looks like a specialty vehicle transportation business (given there are usually various types of luxury cars & limousines parked at the property).
It is in a residential area and on a main public transportation route.
I am concerned because, we have had clear (not raining) weather so far this week, yet the property owners (or current occupants) have yet to paint over the graffiti.
