(A) In any parade, picket line, or group demonstration, it shall be unlawful:
(1) For any minor below the age of 18 years to participate or be allowed to participate. Any person encouraging, leading, or allowing such minor to so participate, unless a permit therefor has been issued, shall be guilty of a violation of this section.
(2) For any person to lead, guide, participate in, or in any way support or encourage such parade, picket line, or group demonstration when a minor below the age of 18 years is pariticipating therein, unless a permit for such participation by the minor has been issued.
(3) For any parent to knowingly permit any minor child of that parent under 18 years of age to participate in such parade, picket line, or group demonstrations, unless a permit for such participation by the minor has been issued.
(4) To cause, participate in, lead, or encourage any parade, picket line, or group demonstration to deviate in any manner from the authority therefor specified in the permit.
(B) Any picket line or group demonstration which participates in any area subject to normally heavy pedestrian or vehicular traffic may be limited in the permit issued to a concentration of not more than six persons participating within any designated areas of the street or sidewalk. However, the officer issuing the permit may specify a larger number in the designated area where, in his judgment, conditions permit a higher concentration. A designated area is defined as the entire width of the street or sidewalk within a distance measured along its length for 100 feet.
(C) The Chief of Police, or in his absence, the next highest ranking police officer shall not issue a permit for a parade, picket line, or demonstration which is scheduled to begin prior to one hour following the scheduled end of any other authorized parade, picket line, or demonstration that takes place at the same location or follows the same or similar route.
