A group of Southern California law enforcement officers who rushed to save lives during a gunman’s deadly rampage in Las Vegas returned home wounded but alive. Yet, while they were hailed for their heroic efforts, there is one benefit they won’t be afforded as they recover physically and psychologically from the Oct. 1 attack: workers’ compensation. Officials in Orange County on Monday denied compensation claims to four off-duty sheriff’s deputies who were attending the outdoor music festival when it turned into a killing field.
