Greece is famous for its ruins, but is its ruined economy set to tip Europe into another banking crisis. Even the dogs on the streets of the Greek capital know tonight's news, fear of a Greek default is forcing Europe's leaders to act to prevent chaos in the financial markets. I'm in Athens where the world famous riot dog is the only one who's staying cool. We look, the world famous riot dog may be resting now, but he and the protesters are prepared for more. On the streets and in the parliament everybody knows this is just the lull.
