IMO the Unites States Congress is the only legislative entity that is allowed to regulate firearms in *any* way.And,of course,any legislation they pass is subject to scrutiny by Federal courts...sidestepping the thousands of petty little dictators in the states’ courts.
Regulating our God Given Rights as outlined in the United States Constitution is not the job of Government, either Federal, State or Local.
In my OP I used the word allowing. That was an error on my part.
Our Constitution is not a Permission Slip.
