Interview with a Murderer

With zero evidence presented, this is reduced to some kind of pointless "battle of wills" motivated by a shared thirst for television celebrity. The criminologist comes across as self-important, manipulative and irresponsible. If Spencer's ex-wife hadn't made a sudden appearance at the end (how this came about is left unexplained), the program would consist of precisely nothing: as it is, it adds a fresh tidbit of hearsay. Is this really how criminology is supposed to work, or just on TV?
