Katz v. United States · ¶22

There is, so far as I understand constitutional history, no distinction under the Fourth Amendment between types of crimes. Article III, § 3, gives “treason” a very narrow definition and puts restrictions on its proof. But the Fourth Amendment draws no lines between various substantive offenses. The arrests in cases of “hot pursuit” and the arrests on visible or other evidence of probable cause cut across the board and are not peculiar to any kind of crime.
