Approximately 10:30 a.m. EST Emotions spill over into violence at a two-hour protest by several hundred to a thousand firefighters near City Hall, beginning at West and Chambers Streets, to protest Giuliani's October 31st ruling to reduce the number of firefighters permitted at the World Trade Center site from 64 to 25. After firefighter Mike Heffernan, brother of John Heffernan, retired fire captain Bill Butler, father of Tommy Butler, and Kevin E. Gallagher, the president of the Uniformed Firefighters Association, speak, the assembled protesters push aside a barricade and begin walking south down West Street. At the next barricade the police move in, punches are thrown, and firefighters handcuffed. Both sides shout for understanding, and the conflict quickly subsides. The firefighters then march out to the applause of construction workers, the protest breaking up around 12:30 p.m.
12 firefighters (including four ranking fire officers and one fire marshal) are arrested and taken to the 28th Precinct station house in central Harlem. 5 police officers are injured, two with black eyes and facial trauma, three with neck, shoulder and back injuries.
