OK, it wasn't a "real" robot, it was a big metal sculpture named Goliath that looked like a robot and really it wasn't mugged but it was vandalized and really it wasn't in San Francisco, it was in Pacific Heights but close enough. The Robot Sculpture named Goliath was vandalized probably by a couple of teens from across the street who had been partying too hard. The robot had actually caused quite a stir in the mega-millions neighborhood because of an apparent uncouth goliath appendage. Over the years a specific appendage has had a bow stuck on it for christmas and some teen was caught trying to cut it off. This year, nothing about the appendage, but instead, the living daylights was beaten out of it (probably with a baseball bat) and the owner Robert Mailer Anderson says, "the sculpture is lucky to be alive!" The vandals caused around $5,000 to $10,000 worth of damage to Goliath. The do-badders were caught on surveillance cameras and a police report was filed but the owner says he won't press charges and he's already received an apology from a likely party (the vandal's parents from across the street?)
