In Unpredictable New York Protests, Organized Criticism of Police

``Some of the protesters are aware of the tactics employed by the Police Department when the Republican National Convention was held in the city in 2004 and hundreds of people were swept up in mass arrests if they congregated in one spot for too long. To avoid that fate, these protesters keep moving. If the police keep them away from the Brooklyn Bridge, a contingent heads toward Times Square. If Times Square is cleared, they head to the Lincoln Tunnel.''
