Once a social engineer has such codes, getting the information he needs is an easy process. In this example, he might begin by calling a clerk in a local state police Teletype office, and asking a question about one of the codes in the manual—for example, the offense code. He might say something like, "When I do an OFF inquiry in the NCIC, I'm getting a ‘System is down’ error. Are you getting the same thing when you do an OFF? Would you try it for me?" Or maybe he'd say he was trying to look up a wpf —police talk for a wanted person's file.
