(1) Loitering or Prowling. No person shall loiter or prowl in a place, at a time or in a manner not usual for law-abiding individuals under circumstances that warrant alarm for the safety of persons or property in the vicinity. Among the circumstances which may be considered in determining whether such alarm is warranted is the fact that the person takes flight upon appearance of a police or peace officer, refuses to identify himself or manifestly endeavors to conceal himself or any object. Unless flight by the person or other circumstances makes it impracticable, a police or peace officer shall prior to any arrest for an offense under this section afford the person an opportunity to dispel any alarm which would otherwise be warranted, by requesting him to identify himself and explain his presence and conduct. No person shall be convicted of an offense under this subsection if the police or peace officer did not comply with the preceding sentence, or if it appears at trial that the explanation given by the person was true and, if believed by the police or peace officer at the time, would have dispelled the alarm.

(2) Obstruction of Highway by Loitering. No person shall obstruct any street, bridge, sidewalk or crossing by lounging or loitering in or upon the same after being requested to move on by any police officer.

(3) Obstruction of Traffic by Loitering. No person shall loaf or loiter in groups or crowds upon the public streets, alleys, sidewalks, street crossing or bridges or in any other public places within the County in such manner as to prevent, interfere with or obstruct the ordinary free use of said public streets, sidewalks, streets, street crossings and bridges or other public places by persons passing along and over the same.

(4) Loitering After Being Requested to Move. No person shall loaf or loiter in groups or crowds upon the public streets, sidewalks or adjacent doorways or entrances, street crossings or bridges or in any other public place or on any private premises without invitation from the owner or occupant, after being requested to move by any police officer or by any person in authority at such places.

(5) Loitering In Public Places. No person shall loiter, lounge or loaf in or about any depot, theater, dance hall, restaurant, store, public sidewalk, public parking lot or other place of assembly or public use after being requested to move by any police officer. Upon being requested to move, a person must immediately comply with such request by leaving the premises or area thereof at the time of the request. [Code § 9.12.]
