Yeah, probably requires national reciprocity law passed. Good!
CCW holders are protected by the Constitution against federal interference or regulation. The feds simply have no authority to meddle in owning and carrying guns. A federal law “allowing” CCW implies that the “Gun Free Zone Act” is valid federal law. But it isn’t valid law. The Gun Free Zone Act is patently unconstitutional.
The Constitution gives the feds no authority to regulate owning and carrying guns and the Constitution is the ONLY valid and legal source of federal authority. The Constitution also goes one step further REMINDING the feds that they are prohibited from infringing on the PRE-EXISTING right to bear arms (Amendment II).
Owning and carrying guns is a states’ issue subject to the will of the people of the state.
