Ah yes, that explains it,

Governor "Brown wielded the prerogative of naming . . . 'exempts' in most arbitrary fashion. He used it as an instrument for emasculating conscription itself. He declared free of military duty more than two thousand justices of the peace and one thousand constables; they were needed . . . to preserve domestic peace in Georgia! No man but Brown, said Howell Cobb, 'ever conceived the idea that justices of the peace who never held court, constables who never served a warrant, and militia officers who had no mess to command, were necessary for the proper administration of the state government.' Brown appointed thousands of men of conscription age to all kinds of states offices, merely to made easy for them the avoiding of military service. No state had ever previously been so well supplied with petty officials, most of them on nominal salaries. In Georgia an enormous increase suddenly took place in in constables, deputy bailiffs, deputy clerks, and assistant postmasters. Since militia officers--by Brown's decree--were exempt, he made countless new appointments of this class School teaching became a suddenly popular profession, Brown having exempted these useful citizens from service at the front. Everywhere little schools sprang up merely to keep this type of slacker out of the training camp. Brown exempted one druggist in every drugstore, with the result that at least one pharmacy came into existance at every crossroad. . . . ."
