The Federal Gun Free School Zones Act limits where an unlicensed person may carry; carry of a weapon, openly or concealed, within 1000 feet of a school zone is prohibited, with exceptions granted in the federal law to holders of valid State-issued weapons permits (State laws may reassert the illegality of school zone carry by license holders), and under LEOSA to current and honorably retired law enforcement officers (regardless of permit, usually trumping State law).
