For nearly 200 days, a large white police bus sat on one of the busiest transit plazas in San Francisco. And during that time, it cost the Mission District police station 44 percent of its monthly overtime budget, according to Captain Sean Perdomo. The bus - a San Francisco Police Department "mobile command unit" - was meant to deter criminal activity like drug use and illegal vending at 16th and Mission streets.
At 10:49 p.m., Lt. Manilla Padilla instructed revelers in the Mission District to disperse, saying, "You have four minutes to leave the area to disperse." The police presence included dozens of officers and sheriff's deputies, equipped and prepared to enforce the dispersal.
