cause and a warrant. Id. at 878, 107 S.Ct. 3164. “[I]t is both unrealistic and destructive of the whole object of the continuing probation relationship to insist upon [a showing of probable cause].” Id. at 879, 107 S.Ct. 3164. In Michigan Department of State Police v. Sitz, 496 U.S. 444, 110 S.Ct. 2481, 110 L.Ed.2d 412 (1990), and United States v. Martinez-Fuerte, 428 U.S. 543, 96 S.Ct. 3074, 49 L.Ed.2d 1116 (1976), the Court held that traffic checkpoints where officers screened vehicles for intoxicated drivers or illegal aliens survived Fourth Amendment scrutiny. In both cases, the Court’s decision resulted largely from the “minor interference” involved in responding to a traffic checkpoint.
