Jack Webb's Sergeant Joe Friday and his partner Frank Smith work a string of high-priced shopliftings hitting Los Angeles department stores. Aired May 3, 1953 on NBC, "The Big Carney" is classic Dragnet: patient legwork, terse interrogations, and the unglamorous grind of real police work, all drawn from actual LAPD case files. Episode 202 of the landmark procedural that taught American crime drama how to tell the truth, only with the names changed to protect the innocent.
