It is unlawful for any person to do any of the following within the village of Metamora:

A. 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 actor takes flight upon the appearance of a police officer, refuses to identify himself, or manifestly endeavors to conceal himself or any object. Unless flight by the actor or other circumstance makes it impracticable, any police officer shall, prior to any arrest for an offense under this section, afford the actor 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 section if the police officer did not comply with the preceding sentence or if it appears at trial that the explanation given by the actor was true and, if believed by the police officer at the time, would have dispelled the alarm; or

B. Either individually or as part of a group of two or more persons to stand or loiter on any sidewalk, parking area, street, or at any place in the village to the hinderance or obstruction of free passage of any person passing on or along any sidewalk or street in the village; or

C. Loiter or remain in or about the area within one thousand feet of the property line of any property used for school purposes unless the actor has a relationship involving custody of or responsibility for a pupil or student, or is attending activities or functions sponsored by the school, or resides within one thousand feet of the school, or is visiting a resident within such area, or has written permission from an authorized agent of the school. Unless flight by the actor or other circumstance makes it impracticable, any police officer shall, prior to an arrest for an offense under this section, afford the actor an opportunity to explain his presence and conduct. No person shall be convicted of an offense under this section if the police officer did not comply with the preceding sentence or if it appears at trial that the explanation given by the actor was true and, if believed by the police officer at the time, would have served as justification of his presence pursuant to this subsection.
