Would You Expect Any Other Outcome?

In the too funny category: Following an underground graffiti event that drew thousands of people to a vacant west Berkeley warehouse on Saturday, September 8, many buildings in the area were tagged leaving their owners and local residents dismayed.
The event, called “Special Delivery” and organized by Endless Canvas, took place in the Carbon Warehouse in the old Flint Ink building at 1350 Fourth Street between 6 p.m. and midnight on Saturday. Over the past few weeks, the interior of the 36,000 sq ft building has been covered with tags and street art by dozens of local graffiti artists. The warehouse, which has been vacant since 1999, has been a draw for graffiti artists for years, but this orchestrated “happening” was seen as a last gasp before the building is cleaned up and put to use by its owner, Alan Varela, owner of ProVen Management.

Based on the full article, 5000 people attended the graffiti convention.  You know the cops and city were aware what was going on but they chose not to do nothing.
What did they expect, the the graffiti thugs would just go home and not do any vandalism?
Another reason not to live in California.
