Friday afternoon, with thousands of protesters already in the streets, one day before a planned, massive march, the 3 metre high, 5 km long concrete and wire wall around the FTAA meeting site, succumbed. Initially, it took the force of only one demonstrator climbing onto it plus several police officers attempting to restrain him for the wire portion to tumble. In the ensuing hour or so, police fired the first teargas followed later by rubber bullets. A scheduled meeting between U.S. President Bush and several leaders as well as the full summit session had to be postponed. In addition, the ventilation system of the summit site had to be shut down because of the entry of police tear gas a few blocks away. During the scuffles, two water cannon trucks brought out to control the crowd were overwhelmed by protesters and had to beat a retreat, some of their windows smashed. The demonstration which resulted in the incidents began as a green march, with non-violent intention, which turned yellow, then red, according to participants at the scene.
