Whether a defendant may suppress evidence obtained through a search directed at him even though the search violated only another person's Fourth Amendment rights.
Holding
No. A defendant may invoke the exclusionary rule only for a violation of his own Fourth Amendment rights, not as a vicarious beneficiary of a violation committed against someone else.
Reasoning
The Court rejected petitioners' proposed “target” theory, under which a criminal defendant could challenge a search simply because police directed it at him. Fourth Amendment rights are personal rights. A defendant is not constitutionally aggrieved merely because damaging evidence introduced against him was obtained by searching another person's property or premises.
The exclusionary rule exists to enforce the Fourth Amendment, not to create a general remedy for every unlawful police search. The person whose privacy or property interest was actually invaded ordinarily has ample incentive to seek suppression if prosecuted or to pursue other remedies if not prosecuted.
Expanding suppression to every intended target of an investigation would also impose substantial practical costs. It would require courts to determine police motives and investigative targets, broaden exclusion of reliable evidence, and produce only marginal additional deterrence beyond the protection already afforded to the person whose own rights were violated. കേസുകൾ such as Jones, Jeffers, and Bumper did not establish the broader target theory petitioners asserted.
