Employees of an automobile dealership in San Diego had become increasingly disturbed by a co-worker’s behavior. After the mass killing in Las Vegas in October, this service adviser praised the shooter for not committing suicide until he had gunned down enough victims to set a modern record.

“If I were him,” the service adviser volunteered, “I would have shot up a mosque and then shot it out with cops.”

Not long after, he boasted that if he were fired by the car dealership — a prospect that seemed likely — he would return with his gun. An alarmed co-worker notified police and statements were taken. My office obtained a GVRO, and the man surrendered a semiautomatic rifle with significant killing capability.
