It’s funny, because law enforcement agencies around the country don’t seem to have any problem dealing with this issue. I can see where there might be some problems though, in that state boundaries inside the park might not be well delineated everywhere, but that problem certainly isn’t unique to National Parks. There’s also issues with federal facilities:
Not only that, but the feds have their own rules and regulations. One prohibits guns in federal buildings or facilities, but just what constitutes a federal facility isn’t clear.
“A visitor center is an easy one,†Nash said. “Our administration building is another easy one. It’s not clear to us at this point … [if] every structure would be classified as a federal facility even though we own it.â€
The uncertainty extends to concessionaires too. Is a building still a federal facility if it is run by a private company?
Actually, this is something that should be deflined more clearly across the board, but what constitutes a federal facility is pretty clearly defined in 18 USC 930:
The term ”Federal facility” means a building or part thereof owned or leased by the Federal Government, where Federal employees are regularly present for the purpose of performing their official duties.
So if the concessionaires are not federal employees, they aren’t federal facilities. Outhouses, under this guideline, would also not be considered federal facilities, because federal employees are not regularly present. Of course, the law also says:
(h) Notice of the provisions of subsections (a) and (b) shall be posted conspicuously at each public entrance to each Federal facility, and notice of subsection (e) shall be posted conspicuously at each public entrance to each Federal court facility, and no person shall be convicted of an offense under subsection (a) or (e) with respect to a Federal facility if such notice is not so posted at such facility, unless such person had actual notice of subsection (a) or (e), as the case may be.
So they have to post, or notify you in some other way, in order for them to convict you. But I can see the confusion. Most other agencies wouldn’t have to deal with this problem, since their facilities are more cut and dry.
