Katz v. United States · ¶28

Finally, I do not read the Court’s opinion to declare that no interception of a conversation one-half of which occurs in a public telephone booth can be reasonable in the absence of a warrant. As elsewhere under the Fourth Amendment, warrants are the general rule, to which the legitimate needs of law enforcement may demand specific exceptions. It will be time enough to consider any such exceptions when an appropriate occasion presents itself, and I agree with the Court that this is not one.
