This system can be accessed from computer terminals that have been installed in police cars so that the arresting police officer can have on-the-spot access to identification information. By entering last name, first name,[12] and sex, a police officer can determine if a particular individual is sought on an outstanding arrest warrant or is the subject of a “stop order” provided that the arrestee provides his truthful name or an alias upon which he has previously been arrested. This system also provides access to the State of Illinois criminal justice information network (the “Illinois Law Enforcement Agency Data System,” or “LEADS”), as well as to a national database of wanted persons (the “National Crime Information Center,” or “NCIC”).
