Statham, Georgia, is a town of some 2,400 people on less than 4 miles square on a state highway en route from Atlanta to the University of Georgia in Athens. But one of its police officers, until he left the department in June, routinely arrested dozens of people, usually women, and charged them with driving under the influence simply because they were taking medications prescribed by their doctors that did not impair their driving, according to a new federal lawsuit.

Atlanta attorney Zack Greenamyre said his client, Kelly Pickens, was one of those women.
