How Silicon Valley gun rules changed after the VTA shooting

When a disgruntled employee fatally shot nine coworkers at a Santa Clara Valley Transportation Authority rail yard last year, Silicon Valley officials vowed to take action.

The May 26, 2021 VTA mass shooting is the deadliest gun massacre in the Bay Area’s history, where nine transit workers died from the attack. Another worker, haunted by the event, died by suicide months later.
