The term 'FINGERS IN A LINEUP' can be summarized as a process of identification. This process is known as IDS, which stands for Identification. It is a method used by law enforcement to identify suspects in a criminal investigation. In this process, a lineup of people is presented to witnesses or victims of a crime, and they are asked to identify the perpetrator. The witnesses or victims are asked to point out the suspect by pointing to their fingers in the lineup. This process is used to ensure that the correct person is identified and brought to justice.
