Employer refuses to terminate an employee who threatened to kill a staff member using a gun. What can I do?

This employee was just reinstated after a 6 month investigation and home work assignment for telling multiple people he was going to shoot and kill a co-worker at work. A separation order was put in place between the 2 employees, however the perpetrator has a history of work place violence and pulling a gun in a road rage incident. I don't feel safe. What do I do?
