SF neighborhood, police powerless against car break-ins
Gerry McMahon makes his living as a brick mason, but on the side he's become an authority on car break-ins. He's learned all about one of San Francisco's most rampant, frustrating crimes from a front-row seat - the house where he's worked for the past several months on a stretch of Lombard Street where tourists park. He looks for nondescript four-door vehicles, often silver or white, with blank paper license plates. Cars that never head down the famous curvy section of the street, but instead circle the blocks at the top of the hill - over and over again.
