Reasonable articulable suspicion is described as ___________ probable cause, and is necessary for a _____ Amendment "seizure" when stopping an individual.

Reasonable articulable suspicion is a legal standard used in the context of stops and detentions. It requires that a law enforcement officer has specific and objective facts that lead them to believe that a person may be involved in criminal activity. This legal standard is considered "less than" probable cause, which is the higher standard required for making arrests or obtaining warrants.

In the context of the Fourth Amendment, which protects individuals from unreasonable searches and seizures, an officer can stop and briefly detain an individual if they have reasonable articulable suspicion. This is distinct from probable cause, which refers to a stronger belief that a crime has been committed or that specific evidence of a crime can be found. Therefore, the statement accurately reflects that reasonable articulable suspicion is necessary for a seizure that falls under the Fourth Amendment.

The distinction between reasonable suspicion and probable cause is crucial in law enforcement practices, ensuring that officers act within constitutional bounds while protecting individual rights.
