The most egregious example from the report is the 42 hours of live surveillance conducted during the Outside Lands music festival, which yielded five arrests for theft, pickpocketing, and resisting arrest—and only one of which resulted in the District Attorney’s office filing charges. Despite proponents’ arguments that live surveillance would promote efficiency in policing, in this case, it resulted in a massive use of police resources with little to show for it.
