Stephen Lamarch was riding the subway bound for Manhattan at 2:30 a.m. one Thursday morning when he decided to stretch his legs over the next seat. The only other rider in his car didn't complain. But when two other people stepped onto the car, they did. The two new riders were plain-clothes police officers. "They stepped on the train and said, 'NYPD. You're coming with us,'" Lamarch told reporters. The police pulled him onto the platform and asked him to identify himself and tell them where he was going. They also checked to see if he had any outstanding warrants or was carrying any illegal drugs. After about 15 minutes, they released him with a summons for taking up more than one seat.
