The city’s roughly 11,000 break-ins in the first half of this year resulted in just 86 felony auto burglary cases, about half of which actually ended in a conviction, Jenkins said. Many of those incidents happened in popular tourist destinations like the Marina District, Fisherman’s Wharf and near Civic Center.

In August, an incident at the Palace of Fine Arts epitomized the city’s struggle with the issue when thieves bashed in the window of a rental car that was parked just around the corner from where San Francisco law enforcement officials — including Jenkins and the police chief — were holding a press conference to announce new strategies to crack down on … car break-ins.

“Can you imagine being a tourist, going to a city and not only having your rental car broken into but having your passport stolen … then to return to the city you came from and tell everyone about this bad experience,” San Francisco Mayor London Breed said at the same press event.

Sharky Laguana, CEO of Bandago, a van rental company, who also joined Wiener on Thursday, has far more first-hand experience than most with the city’s car break-in woes.

He said every van in his company’s fleet, often used by touring bands and artists, has been broken into at least two times in the city.

Laguana said he even once chased down a person who broke into one of the vans right in front of him.

“As a car rental company, we see so many of our customers get broken into,” he said. “Customers have lost film gear, music gear. … It’s frustrating how difficult it’s been to find progress on this issue.”

Cassandra Costello, executive vice president of San Francisco Travel, which promotes tourism in the city, applauded the new legislation.

“We need to send a message that auto burglaries are not tolerated in San Francisco,” she told reporters. “Having unnecessary red tape is hurting our ability to prosecute these crimes.”
