Before the pre-holiday shopping weekend comes to a close, here's Jack Webb as Sgt. Joe Friday in three authentic police histories from Dragnet. First, Friday is on the trail of a kleptomaniac in "The Big Shoplift" (originally aired on NBC on October 11, 1951). Then, a safecracker eludes the police in "The Big Safe" (originally aired on NBC on May 1, 1952). Finally, a missing body complicates an armed robbery investigation in "The Big Gone" (originally aired on NBC on November 30, 1954).
