Someone gets an F+ for a Fact Error

I've been studying for a test in this class about modes of TV and film analysis. One the books we have in the class is "Channels of Discourse, Reassembled," edited by Robert C. Allen. The book was published sometime in the early to mid 1990's, so it's woefully outdated. But that's not the biggest problem. Despite there being a line of text missing on page 185, the author of the article "Narrative Theory" made a fairly egregious fact error.

In discussing narrative theory and the concept of the narrator, Sarah Kozloff identifies William Shatner as the narrator of "Rescue 911" and Adam Walsh as the narrator of "America's Most Wanted." (This can be found on page 79.) The problem is that the narrator of "AMW" isn't Adam Walsh, it's John Walsh. Adam Walsh is John Walsh's son that was kidnapped and murdered, directly leading to John Walsh creating the show.

How did that error get by so many people?!
