At least two dozen people wearing masks and some carrying pickaxes and handguns smashed jewelry cases and made off with bags full of items during a robbery at a San Francisco Bay Area jewelry store, authorities said. Video from the Monday robbery shows a stream of people wearing masks covering their entire faces entering the jewelry store and then using the pickaxes to crack the glass cases and clear them out. #sanramon #california #UnitedStates #MirrorNow | Mirror Now
