Negative evidence. Suppose that the evidence of an event B increases the proba- bility of a criminal's guilt; that is, if A is the event that the criminal is guilty, then P(A|B) > P(A). Does the absence of the event B decrease the criminal's probability of being guilty? In other words, is P(A|B°) < P(A)? Prove or provide a counterex- ample.
