The exclusionary rule is being flayed with increasing vigor by a number of unrelated sources and with a variety of arguments. Some critics find it unworkable and resort to empirically based arguments. Others see it as the product of a belated and unwarranted judicial interpretation. Still others, uncertain whether the rule works, are confident that in some fashion law enforcement's hands are tied. Professor Yale Kamisar, long a defender of the exclusionary rule, reviews the current attacks on the rule and offers a vigorous rebuttal. He finds it difficult to accept that there is a line for acceptable police conduct that is below the line of a constitutional violation.
