Here in New York, a federal judge has reversed his own order that had put strict limits on police spying on protests and events. In February, Judge Charles Haight ruled that police must stop the routine videotaping of people at public gatherings unless there was an indication that unlawful activity may occur. Judge Haight had cited two events that the police videotaped — a march in Harlem and a demonstration by homeless people in front of the Upper East Side home of Mayor Michael Bloomberg. But this week Haight said he was vacating the order after city lawyers told him new information on the gatherings. Lawyers for the plaintiffs say they’ll challenge the reversal.
