New York City Police Spied Broadly On Protest Groups
For at least a year before the 2004 Republican National Convention, teams of undercover New York City police officers traveled to cities across the country, Canada and Europe to conduct covert observations of people who planned to protest at the convention, according to police records and interviews. But potential troublemakers were hardly the only ones to end up in the files. In hundreds of reports stamped �N.Y.P.D. Secret,� the Intelligence Division chronicled the views and plans of people who had no apparent intention of breaking the law, the records show.
