Which of the following best describes "reasonable suspicion"?

The concept of "reasonable suspicion" is a legal standard used in law enforcement to justify a temporary stop and investigation of a person based on specific articulable facts or circumstances. It falls between "probable cause" and a mere hunch. When officers have reasonable suspicion, they believe that a person may be involved in criminal activity, but they do not have the clear and definitive evidence required for arrest.

This standard allows officers to act when they observe behavior that may indicate criminal activity, but it does not require them to have conclusive proof or clear evidence, such as that required for a warrant or arrest. Reasonable suspicion can be based on specific facts, the officer's training, experience, and observations that lead to a reasonable belief that a crime may be occurring.

The other options do not accurately capture the essence of reasonable suspicion. A vague feeling lacks the necessary specific foundation for acting; a belief based on a detailed investigation suggests a level of certainty that goes beyond reasonable suspicion; and clear evidence of criminal activity aligns more closely with the probable cause standard rather than the more subjective and lower threshold of reasonable suspicion.
