The opening of the G20 summit caused chaos in Toronto throughout the day yesterday, as protestors set police cars on fire and broke into several businesses. The main group remained on the destructive streak more than four hours after their violence began. Police say the violent protestors dressed in black balaclavas, and used the Black Bloc tactic to evade police. Police were dressed in riot gear as they tried to keep the protestors under control. The summit continues today.
