Behind the chicken houses of a Murrayville farm, a handful of Canaan Baptist Church members lined up Saturday in front of a set of green paper targets. “If I say ‘threat,’ stab back out,” said Rodney Smith, director of the Georgia Firearms and Security Training Academy. Smith and his instructors were leading a training session for the church members, who have been instructed on active threats, situational awareness, carry laws and the use of deadly force.
