(a) No person shall loiter in any public or private place at a time and in a manner not usual for law-abiding individuals under circumstances which warrant alarm for the safety of persons or security of property in the vicinity immediately accessible to such person, giving the actor the benefit of every reasonable doubt.
Without limitation, the following circumstances may be considered in determining whether such alarm is warranted:
(1) The flight of the person upon the appearance of a police officer.
(2) The person’s manifest endeavor to conceal himself or some object.
(3) The systematic checking by the person of doors, windows or other means of access to buildings, houses or vehicles.
(4) The person’s refusal to identify himself.
Unless flight by the actor or other circumstances makes it impracticable, a 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.
(b) For the purposes of this section, “loitering” shall include the following activities: lingering, hanging around, delaying, lurking, prowling, sauntering and moving slowly about, where such conduct is not due to physical defects or conditions and includes acts which are commonly associated with the commission of a crime or the attempt to commit a crime.
(c) Whoever violates any provision of this section is guilty of loitering, a misdemeanor of the first degree.
