 Although the exclusionary rule was originally implemented as a guard for privacy rights, after "United States v. Leon", it has been interpreted by the Supreme Court as a tool for deterring police misconduct.In "United States v. Leon", , the Court had ruled that the exclusionary rule did not require the suppression of evidence seized pursuant to a search warrant that was later determined to be invalid.In "Leon", the police's reliance on the validity of the search warrant was objectively reasonable; thus, excluding the evidence seized in that case would not have deterred any future misconduct on the part of the police.
