Whether the clearing-house slips were admissible as the product of a search incident to a lawful warrantless arrest.
Holding
No. The slips had to be excluded because Beck’s warrantless arrest was not supported by probable cause, making the ensuing search unconstitutional.
Reasoning
The Court treated the validity of the search as dependent on the validity of the arrest. It assumed that, if the arrest had been lawful, the scope of the automobile and person searches did not exceed what was then permissible incident to an arrest. The dispositive question was therefore whether the officers had probable cause at the moment they arrested Beck.
Probable cause exists only when the facts and circumstances known to officers, together with reasonably trustworthy information available to them, would lead a prudent person to believe that the suspect had committed or was committing an offense. It is a practical standard, but it cannot be reduced to police suspicion, discretion, or good faith alone.
The record showed only that an officer knew Beck’s appearance and knew he had a prior record involving clearing-house or gambling offenses. The officer also referred generally to unspecified “information” and “reports” from an unnamed source, but the prosecution never established what the source had said, why the source was credible, or how the information connected Beck to criminal conduct at that time and place.
The officers did not observe Beck commit a traffic violation or any other unlawful act. Nor did the record show that an informant predicted that Beck would be at East 115th Street and Beulah at the relevant time, or that the officers corroborated such a prediction through observations of suspicious conduct. Thus, unlike Draper v. United States, there was no concrete, corroborated information supporting an inference that Beck was currently engaged in crime.
A prior criminal record may be relevant in combination with other facts, but it cannot itself establish probable cause. Holding otherwise would effectively permit police to arrest anyone with a criminal record at will. Because the State failed to disclose sufficient facts about the alleged information and its reliability, the Court could not assess probable cause, and the evidence seized following the arrest was inadmissible under the Fourth and Fourteenth Amendments.
