At the training session in Lawrenceville, just outside Atlanta, about 20 students gathered on a recent Saturday morning to go over basic safety lessons and instructions. They started with orange plastic replica guns as Tigner demonstrated proper stance and grip. They are taught not to put a finger on the trigger until it's time to shoot and to keep the muzzle pointed in a safe direction. Tigner plays to their protective instincts by telling them always to know what is beyond their target so they don't accidentally shoot a young child or another innocent bystander.
