WRONG!
Vermont ALLOWS Open Carry and Concealed Carry in Public Buildings, just not Public Institutions.
The relevant Vermont Statute are:
§ 4003. Carrying dangerous weapons.
A Person who Carries a Dangerous or Deadly Weapon, Openly or Concealed..., within any State Institution or upon the Grounds or Lands Owned or Leased for the use of such Institution, without the Approval of the Warden or Superintendent of the Institution, shall be Imprisoned not more than Two Years or Fined..., $200.00, or both.
§ 4004. Possession of Dangerous or Deadly Weapon in a School Bus or School Building or on School Property.
(a) No Person shall knowingly Possess a Firearm or a Dangerous or Deadly Weapon while within a School Building or on a School Bus. A Person who Violates this Section shall, for the First Offense, be Imprisoned not more than One Year or Fined..., $1,000.00, or both..., etc..
§ 4016. Weapons in Court.
(a) As used in this Section: (1) 'Courthouse" means a Building or any Portion of a Building designated by the Supreme Court of Vermont as a Courthouse.
(b) A Person who, while within a Courthouse [as defined under (a)(1) of § 4016], and without Authorization from the Court..., (1) Carries or Has in His or her Possession a Firearm..., (2) shall be Imprisoned not more than One Year or Fined..., $500.00, or both.
The ONLY PLACES off-limits in Vermont are: 1. State Institutions [Prisons and Mental Health Assylums], 2. Schools [K-12 AND COLLEGES/Universites, whether Public, Private, or Parochial], AND 3. Courthouses [designated as such per (a)(1) of § 4016].
Local Governments may not Ban Firearms in Public Buildings throughout Vermont under Vermont Code § 2295.
§ 2295. Authority of Municipal and County Governments to Regulate Firearms, Ammunition..., etc..
Except as otherwise provided by Law, no Town, City or Incorporated Village, by Ordinance, Resolution or other Enactment, shall Directly Regulate..., the Possession, Ownership, Transportation, Transfer, Sale, Purchase, Carrying, Licensing or Registration of..., Firearms, Ammunition or Components of Firearms or Ammunition. This Section shall not Limit the Powers Conferred upon a Town, City or Incorporated Village under Section 2291(8) [§2291(8) provides: To Regulate or Prohibit the Use or Discharge, but not Possession of, Firearms within the Municipality..., but shall not effect any Sport Shooting Range, as that Term is defined in Section 5227 of Title 10 of this Title]..., The Provisions of this Section shall Supersede any Inconsistent Provisions of a Municipal Charter.
Open Carry, or Concealed Carry, absent Criminal Intent, is Permitted in ALL non-State Facilities in Vermont, in accordance with the clear and unambigous Vermont Laws, as cited above.
Schools are OFF LIMITS!
Furthermore, Banks [to include: Federal AND State Credit Unions] are Legal to Open or Conceal Carry thereupon, BUT they are Private Property, and they can Regulate their Private Property as they wish. Simply put, if you are adked to Leave, you have to Leave when asked.
