I suspect the sheriff wanting a DD214 is to excuse himself from doing his own research...it is his responsibility to validate the truthfulness of an applicant's CHP form.
it is also the sheriffs ball game...he holds the responsibility for total approval/rejection of the CHP and is, by statute, immune from any ramifications for his 'judgement' calls. therefore, if the citizen truly wishes a chp, whose main purpose is to facilitate the purchase of firearms, in lieu of a PPP (also issued by the sheriff) within the tarheel state, then the citizen will produce a dd form 214 as needed.
if rejected, it is the citizen's responsibility to judicially pursue through the county court system.
