/ˈriːzənəbl səˈspɪʃən/ – Phrase
Definition: sự nghi ngờ có căn cứ, sự nghi ngờ có lý.
A more throughout explanation: Reasonable suspicion is a legal standard used in criminal law that refers to the belief that a person may be involved in criminal activity based on specific and articulable facts, which are more than a mere hunch but less than the level of proof required for probable cause.
Example: The police officer had reasonable suspicion to stop and search the vehicle based on the driver’s erratic behavior and the strong smell of marijuana coming from the car.
