Questions

Officer Jоhnsоn wаs pаtrоlling in аn unmarked car on a highway area under surveillance for drug trafficking and saw an overloaded camper truck traveling in tandem with a Pontiac. He radioed for help, and when Officer Kennedy responded, they attempted to stop the two vehicles. The Pontiac pulled over, but the truck continued on, pursued by Officer Kennedy. Once Officer Johnson obtained the identification of the driver of the Pontiac, he tried unsuccessfully to reach Officer Kennedy by radio. Officer Johnson then radioed for more assistance and when additional police officers arrived, he drove to where Officer Kennedy had stopped the truck. After smelling the odor of marijuana coming from the vehicle, Officer Johnson opened it, saw bales of marijuana, and arrested the driver. The entire encounter lasted around 20 minutes. Assume that marijuana is illegal in this jurisdiction.  Was this a valid investigative stop?
