Justice Frankfurter, joined by Justice Jackson, argued that the Fourth Amendment must be read against its historical purpose: preventing the abuses of warrantless and general searches that helped inspire the Revolution. In his view, a search is generally unreasonable without prior judicial authorization unless a genuine necessity justifies dispensing with a warrant.
The narrow search-incident-to-arrest exception rested on necessity, not on the bare fact of arrest. It permitted officers to search the arrestee and the items within his immediate physical control to protect themselves, prevent escape, and prevent destruction of evidence; it did not authorize a search of the premises merely because the suspect was arrested there.
Justice Frankfurter rejected the majority's reading of prior decisions as establishing authority to search the place of arrest. He viewed the earlier cases as supporting searches of the person, seizure of items in plain view, or seizure of objects in the arrestee's immediate control. Extending those principles to a search through an office's desk, safe, and files converted a narrow necessity-based exception into a broad license to rummage.
The officers had known for days that Rabinowitz likely possessed forged stamps, brought stamp experts with them, and had ample time to obtain a search warrant. Those facts showed that the search was planned in advance rather than compelled by the exigencies of an arrest. A magistrate, rather than the police, should have decided whether probable cause justified searching Rabinowitz's papers and effects.
Justice Frankfurter warned that the majority's open-ended reasonableness standard supplied no workable constraint. Allowing a warrantless search whenever officers arrest someone in a room threatens to make the arrest a means of evading the warrant requirement and to erode the Fourth Amendment's central protection of privacy.
