When someone is pulled over for a suspected DUI, the police are usually drawn to the person’s attention because of a traffic violation—for example, speeding, driving too slow for traffic, erratically crossing lines or weaving in a lane, etc. Certainly, police target certain individuals and at certain times of day—in my opinion, a police officer observing a traffic violation of a 20-year-old man driving alone at 2:00 a.m. will likely view that person differently than the same traffic violation being committed by an 80-year-old woman at 4:00 in the afternoon.
