SAN JOSE (KCBS) – The father of one of the victims of San Bernardino terror attack said Apple should cooperate with the FBI and unlock the gunman’s iPhone. He also wants a new law that would require that kind of cooperation in the future.

He doesn’t want to create Big Brother, but Gregory Clayborn told KCBS that he wants Apple to help the FBI get into Syed Farook’s iPhone and catch any co-conspirators.

“Because I don’t want to see this happen to anybody else’s child. No parent should have to bury their child, I had to bury my child,” Clayborn said. His 27-year-old daughter Sierra was a San Bernardino County health inspector, one of 14 people gunned down in the attack.

Clayborn was in San Jose last weekend at the California Democratic Party convention, searching for lawmakers willing to introduce what he calls “Sierra’s Law.”

“We’re really trying to get people to be more accountable, people to be more vigilant, people to be more aware of what’s going on around them on a constant basis. So that people would have a tendency to look twice versus turn a blind eye when they see something that’s not right going down,” he said.
