Probable Cause
Facts and circumstances known to officers that would lead a reasonable person to believe a crime has been or is being committed; can be based on trustworthy informant information if specific and corroborated.
Informant Reliability
Credibility and track record of an informant; reliable informants providing detailed, corroborated information can support probable cause.
Draper v. United States
A 1959 Supreme Court decision holding that an arrest based on detailed, reliable informant information can establish probable cause for arrest and a search incident to arrest without a warrant.
Hereford

Search Incident to Arrest
A search of the arrestee and immediate surroundings conducted to protect officer safety and prevent destruction of evidence, permissible when the arrest is lawful.
Arrest Without a Warrant
An arrest made without a warrant when probable cause exists; permissible under certain conditions but still subject to the Fourth Amendment’s reasonableness standard.
Fourth Amendment
Constitutional protection against unreasonable searches and seizures; governs when arrests and searches may occur and often requires warrants.
Beck v. Ohio
A 1964 Supreme Court holding that an arrest and subsequent search without sufficient probable cause or a warrant violate the Fourth Amendment.
Lack of Probable Cause (Beck reasoning)
Insufficient specific and articulable facts to justify an arrest; general information or vague descriptions are not enough.
Gerstein v. Pugh
A 1975 Supreme Court decision holding that the Fourth Amendment requires a prompt judicial determination of probable cause before extended pretrial detention after an arrest without a warrant; no right to an adversary hearing at arraignment.
Prompt Judicial Determination
A timely, court-based review of probable cause to justify detention after an arrest without a warrant.
48-Hour Rule
The rule that probable cause must be determined within 48 hours of arrest; review can be of a PC affidavit without a formal hearing, and courts must be available on weekends/holidays.
42 U.S.C. § 1983
Civil rights statute enabling suits against state actors (e.g., sheriffs, municipalities) for violations of constitutional rights, such as unlawful detention.
Adversary Hearing
A hearing where the prosecution and defense present opposing arguments on the merits; not required for the initial probable cause determination in Gerstein.
Extended Pretrial Detention
Detention of a suspect for an extended period without timely judicial review of probable cause, which Gerstein aims to prevent.
