n. a law enforcement method used in an attempt to have a witness or victim identify a person suspected of committing a crime. The suspect is included in a line of people, including non-criminals and others (such as plainclothesmen, office clerks, etc.). Law enforcement officials ask each person in the lineup to speak and turn to profile, while the witness or victim studies each of them and then is asked which person in the lineup, if any, committed the crime in his/her presence. One danger with this system is that the officers will suggest by manner or tone which is the suspect, or that one person in the lineup appears, by dress or conduct, to seem more suspicious. This type of identification is precarious at best.
