Which brings me to my all-time favorite Columbo: Murder by the Book. The case against Ken Franklin for the murder of James Ferris depends on proving that the murder described in Ferris’ notes (which Franklin admits “is my idea, the only really good one I ever had,” and that “I must’ve told it to Jim over five years ago”) is, as Columbo tells it, “the part you used, practically word for word.”
We know that’s true because we saw the Ferris murder. But how does a prosecutor prove that the actual murder was committed “practically word for word” as Ferris’ notes described: “A wants to kill B. Drives B to a remote house and has him call his wife in city. Tells her he’s working late at the office. Bang, bang”? What’s the proof that Franklin wanted to kill Ferris? What’s the proof that Franklin drove Ferris to a remote house, or that Ferris called his wife to tell her he was working late at Franklin’s suggestion? To me, that’s the problem with proving Columbo’s theory in court. To prove the theory, you first have to prove that Franklin murdered Ferris. And if you can do that, why bother with the theory?
