Mike had this in his Blog Round Up, but it certainly merits a closer look.
NY Times (reg. req'd.)
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.
From Albuquerque to Montreal, San Francisco to Miami, undercover New York police officers attended meetings of political groups, posing as sympathizers or fellow activists, the records show.
They made friends, shared meals, swapped e-mail messages and then filed daily reports with the department's Intelligence Division. Other investigators mined Internet sites and chat rooms.
From these operations, run by the department's "R.N.C. Intelligence Squad," the police identified a handful of groups and individuals who expressed interest in creating havoc during the convention, as well as some who used Web sites to urge or predict violence.
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.
RNC Intelligence Squad???? That's a division of the NYPD? Is there a DNC Intelligence Squad to spy on Republican counter-protesters? Just how shriveled up and anemic is the 4th Amendment in NYC?
