what is the policy that is in conflict with federal law?
Any entity has the right to control weapons on their property. Your right to carry a weapon does not supercede their rights to control their property.
Title 18 Section 926B states:
Quote:
(a) Notwithstanding any other provision of the law of any State or any political subdivision thereof, an individual who is a qualified law enforcement officer and who is carrying the identification required by subsection (d) may carry a concealed firearm that has been shipped or transported in interstate or foreign commerce, subject to subsection (b).
(b) This section shall not be construed to supersede or limit the laws of any State that—
(1) permit private persons or entities to prohibit or restrict the possession of concealed firearms on their property; or
(2) prohibit or restrict the possession of firearms on any State or local government property, installation, building, base, or park.
You answered your own question but since you really want to carry your gun, you apparently refused to see the answer.
