As CBS News Correspondent Jim Stewart reports, by the time damages were totaled up, the city had lost $2.5 million in actual destruction and businessmen like Tom Wilbur lost thousands more in potential sales.
"We had a police force that was under-manned, under-equipped and over-powered," said Wilbur, produce company manager.
Police say as a result, the protesters now feel emboldened. They've been practicing urban assault techniques ever since Seattle in anticipation of the next big event, the International Monetary Fund meeting next week in Washington where they'll protest what they call "corporate globalization."
And as accustomed as the Washington police are to mass demonstrations, they're preparing for the worst.
Police Chief Charles Ramsey said, "Potentially it could be a huge problem depending on the number of people who show up and what their intentions are."
An estimated 40,000 showed up in Seattle but police don't expect that many in Washington. They do expect massive traffic tie-ups with subway stops and intersections as the key targets as protesters try to shut down IMF headquarters and the World Bank, just two blocks from the White House. But they say they don't expect the rowdiness and window-breaking that went on in Seattle.
"I think non-violence is the only way to go. We are actually concerned about violence. We are against violence," said Han Shan, protest leader.
And for their part, Washington police seem prepared to accept some level of civil disobedience.
"They have a right to demonstrate, but IMF and the World Bank have a right to hold a meeting. And our job is to see that each can go about their business," said Ramsey.
In Seattle the protesters succeeded in shutting down that business but that was largely because police were caught by surprise. This time around, both sides seem to know exactly what the other is up to.
