NEW YORK — Undercover NYPD officers attended meetings of liberal political organizations and kept intelligence files on activists who planned protests around the country, according to interviews and documents that show how police have used counterterrorism tactics to monitor even lawful activities.
The infiltration echoes the tactics the NYPD used in the run-up to New York’s 2004 Republican National Convention, when police monitored church groups, anti-war organizations and environmental advocates nationwide. That effort was revealed by The New York Times in 2007 and in an ongoing federal civil rights lawsuit over how the NYPD treated convention protesters.
