San Francisco’s firefighters union on Monday took a shot at Mayor Mark Farrell over the city’s auto break-in epidemic.

Taking to Twitter, San Francisco Firefighters Local 798 posted a picture of a black SUV’s shattered window with the message: “While at City Hall this happened #citysfine #noproblemshere @MarkFarrellSF @SFGate.”

One of the hashtags seems to reference an internet meme taken from the KC Green web comic “On Fire,” which shows a dog sitting calmly with a cup of coffee as the room is consumed by fire. The dog ironically says, “This is fine.”

Auto break-ins have come under the spotlight after several high-profile incidents, as well as a report that found only 13 arrests have been made over seven years for break-ins reported online. San Francisco District Attorney George Gascón called for $1 million to fund a new auto break-in task force, but most supervisors — as well as Farrell, who was appointed mayor in late January — were unmoved by the plan.

“We do not need another task force,” Farrell told The Chronicle at the time. “We know what the issues are. We simply need action.”

On Tuesday, the new mayor said the status quo on patrolling auto break-ins “is simply unacceptable.”

Farrell added, “Parking your car in San Francisco should not be a game of roulette and is exactly why I asked Chief (Bill) Scott to provide a police department staffing analysis to fix the issue.”

The union did not respond to a request for comment.
