The Lineup was a hard-boiled drama. Like
Dragnet, it realistically showed police doing their jobs. The show always began with a police sergeant ordering suspects to stand at attention so that the victim, behind one-way glass, could try to identify the criminal. While the lineup was rarely the key to solving the case, it did give the show a rhythm and also allowed for humor in the interrogation of the suspects by the sergeant. The series began as a summer replacement for
The FBI in Peace and War in 1950, but soon got its own time slot.
