Law Enforcement Officers Safety Act

Although LEOSA preempts state and local laws, there are two notable exceptions: ``the laws of any State that (1) permit private persons or entities to prohibit or restrict the possession of concealed firearms on their property'' (such as a bars, private clubs, amusement parks, etc.), or ``(2) prohibit or restrict the possession of firearms on any State or local government property, installation, building, base, or park'' Additionally, LEOSA does not override the federal Gun-Free School Zone Act (GFSZA) which prohibits carrying a firearm within 1,000 feet of elementary or secondary schools. Although the GFSZA authorizes on-duty law enforcement officers to carry firearms in such circumstances, off-duty and retired law enforcement officers are still restricted from doing so unless they have a firearms license issued from the state in which they reside and then it is only good for the state in which they reside. Individuals must also obey any federal laws and federal agency policies that restrict the carrying of concealed firearms in certain federal buildings and lands, as well as federal regulations prohibiting the carriage of firearms on airplanes.
