First of all..., The CommonWealth of Virginia has NO Obligation to Enforce Federal Laws.
Secondly, Virginia NEVER has, to the Best of Knowledge, Enforced the Draconian-1000' 'Firearm-Free Safety Zone' that Buffers School Property.
Additionally, Federal Law 18 U.S.C. 922(q)(2)(B)(ii) Exempts any Virginia Concealed Handgun Licensee from this Federal Law, so as long as your Friend HAS a Virginia Concealed Handgun License.
Your Friends' Home and Land are also Exempt from 18 U.S.C. 922(q).
Virginia SEEMS Content on Virginia Code 18.2-308.1, and an Additional Exception Exsists under Virginia Code 18.2-308.1(vii), as it is Enumerated under The Third Pargraph of this Code.
P.S.: Neither Federal Law nor Virginia Law Prohibit Firearms or Weapons in or on College/Universities, and Absent a Specific Criminal Prohibition, such Conduct is Considered 'De-Facto' Legal. However, The Merits of this ARE being Determined under DiGiacinto vs. the Rector and Visitors of George Mason University.
