McCarty, 468 U.S. 420, 436, 104 S.Ct. 3138, 3148, 82 L.Ed.2d 317, 332 (1984). To leave the scene of a traffic stop without express permission would risk being pursued and stopped again. For instance, in this case, if the appellant would have ignored the trooper’s request to produce her license and vehicle registration and driven away from the scene, without first receiving express permission to do so, the trooper mostly likely would have viewed that as evidence of flight and consciousness of guilt sufficient to warrant another investigative stop of her vehicle. See State v. Hernandez, 954 S.W.2d 639, 644 (Mo.App.1997) (<HOLDING>). As stated by the United States Supreme Court
holding that reasonable suspicion justifies an investigatory detention holding that circumstances created reasonable suspicion for investigatory stop holding that a tip may provide the reasonable suspicion necessary to justify an investigatory stop holding that flight from police can help establish reasonable suspicion for an investigatory stop holding that reasonable suspicion is required to prolong a traffic stop after the purpose for which the investigatory stop was instituted has been accomplished
