Report Abuse. If the security guard is licensed by the state to carry a gun, they can. There are levels in most states, and license to carry a gun is one of them. And they have no legal standing beyond that of any citizen, even armed security guards are not police officers.n general security guards are still private citizens for the most part. They can only make citizen arrests and (at least in Georgia) they are only allowed to carry a firearm if they have had the proper training and the gun is in an exposed holster while they are in a security uniform.
