double standards of the nypd

Yesterday, hundreds of Occupy Wall Street protesters were arrested for blocking the roadway when a bottleneck formed on the walkway and a large group of protesters took to the roadway instead, obstructing traffic in one lane for several hours. Yet when a 1992 protest consisting of thousands of off-duty police officers degenerated into what one New York Times article characterized as "a beer-swilling, traffic-snarling, epithet-hurling melee that stretched from the Brooklyn Bridge to Murray Street," blocking traffic on the Brooklyn Bridge in both directions for hours, no one was arrested. Double standards much?
