Vanessa and Casper explore the theme of innocence in chapter seventeen of Harry Potter and the Prisoner of Azkaban. They bemoan how the criminal justice system has betrayed Sirius Black, discuss Ron's prejudice again werewolves, and try and come up with a good metaphor for the chaos of this chapter. Throughout the episode they consider the question: Who do we normally suspect of guilt?
