I just can't see how this doesn't violate the interstate commerce clause. One of the things which the US is is a free-trade zone.

@LiberalLibrarian The late Justice Byron White would have loved that law. He always went out of his way to assert that a child had no rights an adult was bound to respect.

John Kenneth Galbraith was once asked what JFK's greatest mistake was. Without a moment's hesitation, he answered "Byron White."
