Conflict between LEOSA and other laws
Although the general effect of LEOSA is to override state and local law, this is subject to limitations. LEOSA does not override:
state laws permitting private property owners from limiting or prohibiting the carrying of concealed weapons on their property (such as public bars, private clubs, and places such as amusement parks)
state laws prohibiting carrying concealed weapons on state or local government property (such as courthouses, schools or parks)
Although the general exemption from state and local laws is clear, there is debate over the effect and scope of policies issued by individual law enforcement agencies in relation to their own employees, where such policies would appear to restrict the ability of a law enforcement officer to carry a firearm. Some argue that the law does not override the internal policies of a department or agency. However, when LEOSA was under consideration in the United States House of Representatives Committee on the Judiciary, considerable representations were made to the effect that it would override agency-specific policies, leading to opposition to the Act from the International Association of Chiefs of Police, the Police Executive Research Forum, and the United States Conference of Mayors, which was expressed as a dissenting view in the report of the Committee. Congressman Bobby Scott (D-VA) proposed an amendment to the Bill to provide that it "shall not be construed to supersede or limit the rules, regulations, policies, or practices of any State or local law enforcement agency," but this amendment was opposed by the sponsors of the bill, and was rejected by the Committee 21-11, so the enacted law contains no such exception.
LEOSA does not override federal law or federal regulations. Therefore, the prohibition on carrying firearms within 1000 feet of a school contained within the Gun Free School Zones Act of 1995 (which authorizes on-duty law enforcement officers to carry firearms in such circumstances) still applies to off-duty and retired law enforcement officers who would otherwise be allowed to carry firearms under LEOSA. Federal regulations prohibiting the carriage of firearms on airplanes and into federal buildings also continue to apply.
