11/13/14 at 9:00pm and raining. 2 policewomen stopping cars near entrance to Brooklyn Battery Tunnel/BQE. They asked for license only, took it into unmarked car, and returned it, wet from the rain, after 2-3 minutes. I’m a 70 y/o white woman with my husband in the front seat. I was too intimidated to ask any questions. I have no idea how often this roadblock is done, nor why.
