ABSTRACT
If asked to decide which of two people committed a crime, one of the first things we would want to know is how each of them had behaved after the crime was committed. For example, what either of them had said about the crime, how each had reacted to any suggestions that they might have been responsible for it and how each had responded to any questioning about their possible involvement. What makes this information seem relevant to our hypothetical inquiry is the widely-held belief that the guilty and the innocent behave differently.
