Joe sat in his United Parcel Service truck at the company distribution center on Potrero Hill on Thursday waiting for a pickup call. He was listening to the radio about the shootings at YouTube that had erupted just two days before and still had the Bay Area rattled. He shrugged.
Nine months ago, a fellow UPS driver easily walked through the center’s doors with a pair of pistols and a box of bullets, and after gunning down three workers and wounding two others, he shot himself to death. Since then, UPS has changed guard companies and tightened up its policies on metal detectors and bag checks, several workers said.
Joe, a middle-aged driver who used an alias because he said UPS forbids workers from speaking to the media, was skeptical.
