On that day, over 300 buses and four special trains brought protesters in from across the country. BBC estimates that 100,000 protesters took part in a rally near the UN headquarters. Among those taking part was the &lt;a href="September%20Eleventh%20Families%20for%20Peaceful%20Tomorrows"&gt;9/11 Families For Peaceful Tomorrows&lt;/a&gt;, a group made up of some relatives of victims of the attacks on the World Trade Center. Speakers included politicians, church leaders and entertainers, such as actress Susan Sarandon and South African Anglican Archbishop Desmond Tutu. As people tried to reach the rally area they ended up constituting an unplanned march, stretching twenty blocks down First Avenue and overflowing onto Second and Third Avenue. In total estimates range from 300,000 to 400,000 protesters (WSWS estimate). The protests were largely peaceful though a small group of protesters who were reported to have broken off from the main rally, caused damage to property in Union Square, and threw stones at police officers, which resulted in forty arrests.
