field show-up
n.— «With closing arguments set to begin today, the case against 10 Long Beach youths accused of beating three white women Halloween night hinges almost entirely on identifications made in a Ralphs parking lot the night of the attack. In a procedure known as a field show-up, police told the victims and a reputed witness that the youths—nine girls and a boy, ages 12 to 17—were suspects and asked if they recognized them from the melee.» —“Key tactic in hate-crime case assailed” by Joe Mozingo Los Angeles Times Jan. 17, 2007.
