A criminology question

          Watch the youtube video, below. According to this chapter, do you believe the law enforcement officer had sufficient "reasonable suspicion" to pull over the driver of the vehicle shown in the video because he was drunk or committed a traffic offense? If yes, explain why. Was it lawful for the police officer to order the driver to step out of the vehicle during this traffic stop? Explain and identify the case law to support your answer. Do you think it was appropriate for the officer to subject the driver of the truck to a field sobriety test to determine if he was driving while intoxicated? Explain. https://youtu.be/D6VQDNIZH7U
