Seventy years ago, in the famous Weeks case,' the Supreme Court evoked a storm of controversy by promulgating the federal exclusionary rule. When, a half-century later, in the landmark Mapp case,2 the Court extended the Weeks rule to state criminal proceedings, at least one experienced observer assumed that the controversy "today finds its end." 3 But as we all know now, Mapp only intensified the controversy. Indeed, in recent years spirited debates over proposals to modify the exclusionary rule or to scrap it entirely have filled the air - and the law reviews.'
