I was reading through the GFSZA and found an interesting bit of info there. It says that as long as you have a permit to carry in the state which the school zone is located then you are exempt from the GFSZA. I know that if I conceal and go to my sons school and someone finds out then all hell will break loose but I have the law on my side. Am I interpreting this law correctly? I have looked in several different places to confirm this but am still skeptical. I linked to a letter from the ATF about this issue.
