(a) The Mayor may, in case of riot or insurrection, or when there is a clear and present danger of a riot or insurrection, proclaim in writing a state of emergency.
(b) As part of such proclamation or by subsequent written order after such proclamation is issued, the Mayor may, in his discretion as he deems necessary to the public safety:
(1) Delineate the boundaries of any area threatened by riot or insurrection, and restrict or prohibit the movement of persons into, from or within such area.
(2) Establish a curfew within such area, and prohibit persons from being out of doors during such curfew.
(3) Prohibit the sale, offering for sale, dispensing and transportation of firearms and other deadly weapons, ammunition, dynamite and other dangerous explosives, incendiary devices and any necessary ingredient thereof.
(4) Issue reasonable regulations to suppress such riot or insurrection, or to protect persons or property from harm by reasons of such riot or insurrection.
(c) When the danger from riot or insurrection is past, the Mayor shall forthwith make proclamation that the emergency has ended and any proclamation, order or regulation issued pursuant to this section shall then become void.
(d) The powers conferred by this section are in addition to any other power which may be conferred by law and nothing in this section shall be construed to modify or limit such authority, power, duties and responsibilities of any officer or public official as may be provided by law. Nothing in this section shall be construed to permit the suspension of the privilege to a writ of habeas corpus.
(e) Whoever violates any proclamations or written orders of the Mayor is guilty of a misdemeanor of the first degree.
