FED FIREFIGHTER PLEASE READ - If you are ignorant, this is where it is....Sorry.
You need to read paragraph 18 of the Mississippi Code, section 45-9-101 below. It is the statue that allows you a permit:
(18) Nothing in this section shall be construed to require or allow the registration, documentation or providing of serial numbers with regard to any stun gun or firearm. Further, nothing in this section shall be construed to allow the open and unconcealed carrying of any stun gun or a deadly weapon as described in Section 97-37-1, Mississippi Code of 1972.
You also need to read the Mississippi Constitution granting the legislature the right to regulate concealed weapons:
“The right of every citizen to keep and bear arms in defense of his home, person, or property, or in aid of the civil power when thereto legally summoned, shall not be called in question, but the legislature may regulate or forbid carrying concealed weapons.”
The Attorney General is saying you have to carry it completely concealed because the statue that gives you authority to carry it requires that it be concealed and not openly carried. He is also saying the the other section (97-37-1) is the one that defines concealed as "in whole of in part," but that it does not apply to those required to be concealed by the other statutue.
I do not agree with this and it has to be fixed with legislative action and as another responder said, it will take organizations with power to get involved. We can't fix it by ourselves.
