What Is Lineup?

In a legal context, a lineup (or police lineup) refers to a process in which a suspect in a crime is placed with a group of other individuals so that a witness or victim can identify the perpetrator.

This procedure is used in criminal investigations to gather evidence and establish the identity of suspects involved in criminal activities.

Lineup Explained

A lineup typically involves a live presentation or a photo array where the suspect is presented alongside individuals with similar physical characteristics, to prevent undue influence on the witness’s identification.

The process must be conducted fairly to avoid suggestive or leading practices that could influence the witness's decision or result in misidentification.

Lineups are subject to specific legal standards to ensure they are conducted in a manner that protects the suspect's rights and the integrity of the identification process.

The Term Lineup in Different Legal Contexts

Criminal Procedure: A critical part of evidence gathering and suspect identification in criminal cases.

Constitutional Law: Concerned with ensuring that lineups do not violate the suspect’s constitutional rights, such as the right to due process.

Common Misconceptions About the Meaning of Lineup

Many people believe that an identification in a lineup is conclusive proof of a suspect’s guilt. However, lineup identifications are just one piece of evidence in a criminal investigation and must be corroborated by other evidence.

Misidentifications can and do occur, leading to wrongful convictions, which is why the legal system requires careful consideration of lineup procedures and their reliability.
