Our whole family sat around the television watching the concluding episode of The Fugitive. We each guessed who we thought had done the murder that the fugitive had spent so long pursuing while avoiding the law. Toward the end of the show, right before the commercial break, one of the characters indicated he had a confession to make. We kids took that immediately to mean that he was the killer. But my parents said not to be so sure. And in fact the confession was just that he had seen who had done the murder and never reported it, not done it himself.
Similarly, there was an episode in The Rifleman where a fellow comes to town who seems like a nice fellow, befriends the rifleman’s son and his friends, and when there was trouble we kids couldn’t imagine this nice guy being the culprit. But our parents saw what we didn’t, either because they knew the character, or they knew how TV shows played out.
