In the latest clash over the NYPD's stop-and-frisk policy, a new lawsuit is seeking to stop the city from keeping a huge database of New Yorkers stopped, but never charged. The New York Civil Liberties Union is leading the case, in which two men are suing to clear their names from the stop-and-frisk database. Attorney Chris Dunn says the police have refused to seal the records of people who were stopped and released during police checks, despite a state law requiring the NYPD to do so. He says there are about 100,000 people who remain in the database, and are often treated as suspects by the police.
