Gunman Ian David Long, yet another to perpetrate a mass shooting in the US, killed 12 people after launching an attack at a bar in southern California

THOUSAND OAKS, Calif. (AP) — Barely a year after surviving a massacre at a country music festival in Las Vegas, Brendan Kelly found himself in a terrifyingly familiar scene. Kelly, 22, said he was dancing with friends at a bar in suburban Los Angeles on Wednesday night when the bullets began flying. When the gunfire was over, 12 people were dead, including a Navy veteran who had lived through the deadliest mass shooting in modern U.S. history a year ago. "I already didn't wish it on anybody to begin with for the first time," Kelly said outside his home in Thousand Oaks. "The second time around doesn't get any easier."
