The sign may also specify that persons in violation may be denied entrance to the building or be ordered to leave the building. Any ordinance adopted by county governments relating to possession in police stations or county buildings shall also state that any person who immediately foregoes entry or immediately exits such building due to the possession of a firearm, ammunition, components of firearms, or explosives shall not be guilty of violating the ordinance. County governments may establish penalties for any intentional violation of such ordinance as deemed necessary to protect public safety. An ordinance adopted by the county government shall not prevent the following in county buildings or police stations: (1) possession of firearms, components of firearms, and ammunition or explosives by law enforcement officers;(2) law enforcement agencies receiving shipments or delivery of firearms, components of firearms, ammunition or explosives;(3) law enforcement agencies conducting firearms safety and training programs;(4) law enforcement agencies from conducting firearm or ammunition public safety programs, donation, amnesty, or any other similar programs in police stations or municipal buildings;(5) compliance by persons subject to protection from abuse court orders;(6) carrying firearms and ammunition by persons who hold a valid license pursuant to either § 1441 or § 1441A of Title 11 of the Delaware Code so long as the firearm remains concealed except for inadvertent display or for self-defense or defense of others;(7) officers or employees of the United States duly authorized to carry a concealed firearm;(8) agents, messengers and other employees of common carriers, banks, or business firms, whose duties require them to protect moneys, valuables and other property and are engaged in the lawful execution of such duties.(e) For the purposes of this section, "county building" means a building where a county government entity meets in its official capacity or containing the offices of elected officials and of public employees actively engaged in performing governmental business but excluding any parking facility; provided, however, that if such building is not a county owned or leased building, such building shall be considered a county building for the purposes of this section only during the time such government entity is meeting in or occupying such a building.Amended by Laws 2015, ch. 166,s 1, eff. 8/17/2015.22 Del.
