In criminal procedure courses, few cases are as foundational as Terry v. Ohio, 392 U.S. 1 (1968). This Supreme Court decision introduced the legal framework for "stop-and-frisk" encounters—limited searches and seizures by police without a warrant or probable cause. It's a vital case for law students because it represents a balancing act between public safety and individual constitutional rights.

The Facts of the Case

Cleveland Police Detective Martin McFadden observed three men—Terry among them—acting suspiciously near a store. Believing they were "casing" the location for a robbery, McFadden approached the men, identified himself, and conducted a quick search of their outer clothing (a "pat-down"). He found a concealed weapon on Terry.

Terry was charged with unlawful possession of a firearm and argued that the evidence should be excluded because the search violated his Fourth Amendment rights against unreasonable searches and seizures.

The Legal Issue

Does a police officer violate the Fourth Amendment by stopping and frisking a person without a warrant and without probable cause to arrest?

The Supreme Court’s Holding

The Court ruled 8-1 in favor of the State, holding that the search was reasonable under the Fourth Amendment. The majority opinion, authored by Chief Justice Earl Warren, established that:

A limited search for weapons is permissible when an officer has a reasonable suspicion that criminal activity is afoot and that the person may be armed and dangerous.

This new standard—reasonable suspicion—is lower than probable cause but still must be based on specific, articulable facts and rational inferences.

Why Terry v. Ohio Matters

• Creates the “Stop-and-Frisk” Doctrine

Terry formalized the idea that police can briefly stop and pat down a person without probable cause, provided they have reasonable suspicion. This has become a routine aspect of law enforcement and is central to police-citizen encounters.

• Defines “Reasonableness” Under the Fourth Amendment

The case underscores that not all searches require probable cause or a warrant—only that the government’s action be “reasonable” in context. It marked a shift toward more flexible, pragmatic Fourth Amendment analysis.

• Raises Ongoing Debates on Civil Liberties

Terry remains at the heart of public discussions on racial profiling, policing practices, and civil rights. It is frequently cited in litigation and policy debates involving law enforcement discretion and accountability.

• Teaches Doctrinal Balancing

Law students learn how courts balance individual rights with government interests. Terry exemplifies the legal reasoning involved in crafting workable standards for complex real-world situations.
