Define showup, lineup and photographic lineup. Indicate what level of proof the police must have to detain someone to participate in each

Question

What will be an ideal response?

Answer 1

A showup usually involves showing one suspect to the person who is to make the identification. This can be done in the field, at a police facility, or when necessary, at a hospital. If done in the field, the police need reasonable suspicion in order to detain the suspect while the witness is transported to the location where the suspect is being detained. If the procedure is done at a police facility or a hospital, the police must have probable cause in order to detain the suspect and transport him/her to the location where the procedure will be conducted.
A lineup is a procedure in which an eyewitness is asked to view a group of people and select the one who committed the crime or indicate that the criminal is not there. The lineup is normally conducted at a police facility in order to arrange for an adequate number of participants. The police must have probable cause to detain the suspect and transport him/her to the police facility.
Photographic lineups involve showing pictures. The suspect is frequently not in custody when this is done. It may be done by handing the witness a few carefully selected photographs or by allowing him or her to look through mug books or school yearbooks. There are no Fourth Amendment rights involved because there is no detention.
