William J. Brennan, Jr., Kaufman v. United States — Opinion of the Court
“ More fundamentally, the logic of his dissent cannot be limited to the availability of post-conviction relief. It brings into question the propriety of the exclusionary rule itself. The application of that rule is not made to turn on the existence of a possibility of innocence; rather, exclusion of illegally obtained evidence is deemed necessary to protect the right of all citizens, not merely the citizen on trial, to be secure against unreasonable searches and seizures. ”
