 Justice Stewart points out that the Court noted in "Katz v. United States" that the Constitution does not provide individuals with any right to privacy.Rather, the constitution merely provides protection to individuals from government intrusion pursuant to the Fourth Amendment.As a result, Justice Stewart takes exception to Justice Brennan's implication that had there been some dissemination of the information collected in accordance with the New York statute the state would have to show that the statute is necessary to achieving its compelling state interest-curtailing illegal drug use.
