Reasonable Suspicion And Probable Cause in Criminal Defense

When it comes to criminal defense, understanding the concepts of reasonable suspicion and probable cause is crucial. These legal terms play a vital role in determining the legality of actions taken by law enforcement officers in the criminal justice system and whether someone may be held criminally responsible for an act.

Reasonable Suspicion

Reasonable suspicion is a legal standard that allows a police officer to detain and briefly question an individual if they have specific and articulable facts or circumstances that give rise to a suspicion of criminal activity. However, it is important to note that reasonable suspicion falls short of probable cause, which is required for a full search or arrest.

The term “reasonable suspicion” was first mentioned in the landmark case of Terry v. Ohio, 392 U.S. 1 (1968). In this case, it was established that an officer may conduct a brief stop and frisk of an individual if the officer has reasonable suspicion that the person is involved in criminal activity and may be armed and dangerous.

For an officer to have reasonable suspicion, he or she must be able to articulate specific facts and circumstances that support the belief that a crime is being committed or about to be committed. A mere hunch or gut feeling is insufficient to justify an investigatory stop.

Probable Cause

Probable cause is a higher standard than reasonable suspicion and is required for a search warrant or an arrest. Based on the facts and circumstances presented, it is the level of suspicion that a reasonable person would have. Unlike reasonable suspicion, probable cause requires more than just a specific articulable suspicion of criminal activity.

To establish probable cause, the officer must have enough evidence to believe that it is more likely than not that the individual has committed a crime. This evidence can include witness statements, physical evidence, or other corroborating information that links the individual to the alleged criminal activity.

It is important to note that the Fourth Amendment to the United States Constitution protects individuals from unreasonable searches and seizures. This means that to conduct a legal search, the officer must have probable cause.

The Difference Between Reasonable Suspicion and Probable Cause

While both reasonable suspicion and probable cause are legal standards that allow law enforcement officers to take specific actions, there are critical differences between the two.

Reasonable suspicion is a lower standard that allows an officer to briefly detain and question an individual based on specific facts and circumstances that give rise to a suspicion of criminal activity. It is a threshold that is lower than probable cause but still requires some level of factual support.

Probable cause, on the other hand, is a higher standard that requires more evidence and a stronger belief that a crime has been committed. 

It is important for individuals to understand their rights when it comes to encounters with law enforcement officers. If an individual believes their rights have been violated, seeking legal counsel and consulting with a criminal defense attorney is essential. Such a consultation may be the difference between freedom and a prison sentence.

The Threshold of Reasonable Suspicion and Probable Cause

The United States Supreme Court has played a crucial role in defining and interpreting what constitutes probable cause and reasonable suspicion in the context of criminal investigations and searches. Over the years, landmark decisions by the Supreme Court have set important precedents that guide law enforcement activities and protect individuals’ Fourth Amendment rights against unreasonable searches and seizures. 

The Court has also clarified that probable cause requires more than mere suspicion or hunch but does not require proof rising to the level of probable cause or beyond a reasonable doubt. As a result of these cases, law enforcement agencies must meet a certain threshold of evidence before conducting searches or making arrests, safeguarding individuals’ rights while allowing for effective crime prevention and investigation. 

The Precedent in Probable Cause

An example of probable cause can be found in the Supreme Court case of Illinois v. Gates, 462 U.S. 213 (1983). In this case, the police received a letter from an anonymous informant stating that Mr. Gates and his wife were involved in drug trafficking. The letter provided detailed information about their planned trip, their vehicle, and the location of the drugs they were allegedly transporting. The police corroborated some information in the letter, such as the vehicle description and the planned trip. While the informant’s reliability was questioned, the Supreme Court held that the circumstances provided enough information to establish probable cause to search the Gates’ vehicle. 

This case set an important precedent by establishing that probable cause can be based on a combination of factors, even if the informant’s reliability is not independently established. It clarified that the focus should be on the information’s overall reliability, considering its veracity and the surrounding circumstances.

The Precedent in Reasonable Suspicion

As mentioned before, an example of reasonable suspicion can be seen in the landmark Supreme Court case, Terry v. Ohio

In this case, the Court affirmed that for an officer to conduct a brief stop and frisk, there must be reasonable suspicion of criminal activity. The Court held that reasonable suspicion requires specific and articulable facts that an officer can articulate to justify the intrusion on an individual’s Fourth Amendment rights. In Terry, the officers observed the defendants, Terry and Chilton, acting suspiciously in front of a store and believed they were casing the joint for a potential robbery. Based on their training and experience, the officers suspected the defendants were armed and dangerous. 

The Supreme Court determined that the officers had a reasonable suspicion allowing them to briefly stop and frisk Terry and Chilton, which led to the discovery of concealed weapons. This case established the standard for reasonable suspicion and the legality of stop-and-frisk searches.
