The Justice Department has told a federal court that lawful self-defense carry is permitted in ordinary national park buildings open to the public, including visitor centers and shops. But the National Park Service is still telling visitors that federal law prohibits firearms in those facilities.
That contradiction puts gun owners in the middle of two conflicting federal messages about exercising a fundamental right.
In its October 2 filing in Zimmerman v. Blanche, DOJ seeks dismissal for lack of standing, arguing the plaintiffs face no credible threat of prosecution under 18 U.S.C. §930(a) for the lawful carry they describe. It calls the application of its earlier post-office interpretation to that conduct “self-evident.”
For Americans who carry a handgun daily, the issue is straightforward: stopping for a park map or buying supplies should not mean surrendering the ability to defend yourself.
The Lawsuit Behind DOJ’s Concession
AmmoLand covered the lawsuit when it was filed on March 27. Texas gun owner Gary Zimmerman, Firearms Policy Coalition, and the Second Amendment Foundation challenged restrictions on carry in National Park Service facilities and restrictions imposed under 36 C.F.R. §1.5.
Zimmerman alleged that he repeatedly had to disarm before entering park facilities. The original complaint also described having to disarm during a visit to Mammoth Cave, including for a cave tour.
The plaintiffs’ constitutional argument attacked the government’s expansion of “sensitive places” under the Supreme Court’s Bruen decision. Federal ownership should not become a convenient excuse for turning ordinary public destinations into places where peaceable Americans lose their right to bear arms.
FPC’s case page now lists Lisa Ventura as an additional plaintiff and identifies the case as Zimmerman v. Blanche, formerly Zimmerman v. Bondi.
Self-Defense Is a Lawful Purpose
DOJ’s position rests on §930(d)(3), the exception to the federal-facility prohibition for lawful carrying incident to hunting or other lawful purposes.
AmmoLand reported in August that DOJ’s Office of Legal Counsel had applied that exception to self-defense carry in publicly accessible post offices. Its August 12 opinion explains that a person can have a lawful reason to enter a facility and a lawful reason to carry without those purposes being specially connected. ammoland.com
The opinion also expressly discusses national parks. It criticizes an interpretation that lets someone carry on parklands but requires disarming before entering a building, leaving that visitor vulnerable and potentially exposing the firearm to theft. justice.gov
DOJ now argues that the OLC interpretation binds the Executive Branch and covers the plaintiffs’ proposed carry in public park facilities. The person must lawfully possess and carry a constitutionally protected firearm for self-defense in a facility generally open to the public.
That recognizes what gun owners have argued for years: self-defense is a lawful purpose, and walking through a visitor-center door does not change it.
NPS Guidance Still Describes a Gun Ban
As reviewed October 6, the National Park Service’s firearms guidance still describes a federal prohibition, unless expressly authorized, in facilities including visitor centers, ranger stations, fee collection buildings, government offices, and maintenance facilities.
The same page says park visitors’ firearm possession must comply with applicable law and explains that state and local requirements can change within parks crossing jurisdictional boundaries. home.nps.gov
The conflicting building guidance needs correction. If DOJ says lawful self-defense carry is permitted, visitors should receive clear, consistent instructions from the agency operating those buildings. A favorable court filing means much more when the government’s public instructions reflect it.
What Remains Unresolved
This motion supplies no judicial ruling or injunction. DOJ is asking the court to dismiss the case; its interpretation does not repeal §930 or establish unrestricted carry in every federal building.
Federal court facilities have separate restrictions. The OLC opinion also does not establish permission to enter secured or nonpublic areas, or excuse unlawful firearm possession or carry. justice.gov
Separately, DOJ says the compendia for the 15 parks Zimmerman intends to visit contain no firearm restrictions imposed under §1.5. That claim concerns those parks, rather than every park nationwide. assets.nationbuilder.com
Under the Northern District of Texas’s ordinary 21-day response rule, the plaintiffs’ response would be due October 23 unless another rule or court direction changes the schedule. United States District Court
This is a significant concession for armed Americans. The next test is whether the federal government follows through with clear instructions that respect lawful carry. Gun owners should not have to reconcile contradictory federal messages to exercise a constitutionally protected right.
