democracy and protest

Remember the riots in 2002? Some protester threw a bottle and the police reacted? Here's the police footage of that riot. Scenes from Nazi film footage has been added for ideological effect, but it's otherwise pretty damning. If there was a bottle (no evidence of it), that wasn't the reason. It was just the line they used. Their own words, on their own video tape, explain why they used excessive force.

This stuff bothers me. What's wrong with this country? It's beginning to look a lot like some of the countries we hold up as "needing democracy" -- when will it change? And what are we doing to make it better?
