Chatrie v. United States · ¶89

If this weren’t trouble enough, we’ve also adorned Katz with an equally indefensible qualification called the third party doctrine. Under its terms, the Court has held, an individual maintains no “reasonable expectation of privacy” in information he shares with others. Accordingly, the government may freely search a person’s papers and effects without triggering any Fourth Amendment scrutiny so long as they are entrusted to the care of someone else. See Smith v. Maryland, 442 U. S. 735, 743–744 (1979); United States v. Miller, 425 U. S. 435, 442–443 (1976).
