Chaos in TO

The G20 wasn't supposed to be this way, unfortunately, violence has erupted in the city of Toronto.  I was able to witness some of it.  Was peacefully, having a slice at Pizza Pizza on Yonge and Elm when suddenly the windows were smashed in by black clad persons, as groups of protesters and maybe onlookers walked past and amazingly were calmly taking pictures while all these were happening.  The sound of breaking glass was frightening.  All of us patrons inside rushed back to the kitchen.  It was quite a tense moment as we were all watching these black clad persons finish up the whole front windows.  Unbelievably, not three minutes has passed after these black clad persons were gone, a customer comes into the shop with all it's broken windows and patrons huddled in the back kitchen and orders a slice of pizza.  Are Canadians cool or what?
