Fair for Its Day: In "The Return of the Black Shadow", Jim, Cooper, and his sister are attacked by a violent motorcycle gang, who also rape Coop's sister. While she is portrayed as a rather matronly School Marm type and the rest of the episode focuses instead on Jim and Cooper's revenge on the gang, she is never blamed or shamed for what happened to her, and the crime is treated with the seriousness it deserves.
Values Dissonance: In "The Hammer of C Block", it's revealed at the end that Gandy's girlfriend Lila, whose death Gandy had been framed for, actually had committed suicide, after having been beaten regularly by Gandy, then fleeing and returning to him several times. After this is revealed, Jim tries to comfort Gandy, saying that he somehow wasn't to blame for what he did because she kept "[coming] back". Yikes. What the Hell, Hero? indeed. Contrast with Fair for Its Day above and Values Resonance below.
Values Resonance: In "Three Day Affair with a Thirty Day Escrow", the married daughter of an Arab sheik is condemned to death by her father, for having an affair with a gigolo who was part of a real estate scheme (but who had fallen in love with her anyway). Things get worse when her husband turns up murdered and the gigolo is a suspect. Surrounded by all the people involved (including the woman's sympathetic brother), Rockford makes a point of the obvious Double Standard enforced by the father and his men (as the husband had been partying and carrying on affairs himself without punishment), and figures out the murderer (the gigolo's boss and head of the scheme), before causing an explosion on the landed plane they're all on and saving the woman from her fate. This aired in 1978. And only a few years after the Values Dissonance example above. The relevance of the issues discussed has only increased since then.
