Does a vehicle stop violate the Fourth Amendment?

We conclude the vehicle stop did not violate constitutional safeguards against unreasonable search and seizure. "A detention is reasonable under the Fourth Amendment when the detaining officer can point to specific articulable facts that, considered in light of the totality of the circumstances, provide some objective manifestation that the person detained may be involved in criminal activity." ( People v. Souza, supra, 9 Cal.4th 224, 231, 36 Cal.Rptr.2d 569, 885 P.2d 982.) Here the underlying facts for the stop were specific and reliable. The court did not err when it denied the motion to suppress evidence from the vehicle stop.
