Gun Free Zone
I believe the federal law exists only in case the state does not create their own law.
Clearly, Virginia has a law on the books that allows guns on school property while it is in contradiction with of federal law.
The Federal Gun Free School Zone Act of 1990 severely limits where a person may legally carry a firearm by generally prohibiting carry within one-thousand (1000) feet of the property-line of any K-12 school in the nation. A State-issued permit to carry may exempt a person from this restriction depending on the laws of the State, and most issuing States qualify for this exception. However, according to ATF the exemption in Federal law is only applicable to permit holders while in the issuing State, and does not exempt travelers with out-of-state permits, even though the State may honor their permit through reciprocity agreements.
