Sounds as if the police may have been looking for somebody in particular or people matching a description. Or, if it was a roadblock looking for DUI's (drinking or drugs) opening a window so he could smell your breath and see the dilation of your pupils satisfied his inquiry. We have state patrol officers and local police officers who are specially trained to make determinations of drug impairments. One good reason not to be under the influence if you're all dolled up. Heck of a booking picture.
