REMEMBER HOW WE HEARD ABOUT THE DANGERS OF THE ENTIRELY NONVIOLENT TEA PARTY PROTESTS? But will we hear the same clucking-of-tongues about the G20 riots?

The marchers included small groups of self-described anarchists, some wearing dark clothes and bandanas and carrying black flags. Others wore helmets and safety goggles.

One banner read, “No borders, no thanks,” another, “No hope in capitalism.” A few minutes into the march, protesters unfurled a large banner reading “NO BAILOUT NO CAPITALISM” with an encircled “A,” a recognized sign of anarchists.

The marchers did not have a permit and, after a few blocks, police declared it an unlawful assembly. They played an announcement over a loudspeaker telling people to leave or face arrest and then police in riot gear moved in to break it up.

Protesters split into smaller groups. Some rolled large metal trash bins toward police, and a man in a black hooded sweat shirt threw rocks at a police car, breaking the front windshield. Protesters broke windows in a few businesses, including a bank branch and a Boston Market restaurant.

Nothing like this at the Tea Parties.

More here: “The peaceful protesters started throwing rocks at police and police cars, and dragging trash containers into the middle of the street to block traffic. No surprise, the police fired canisters of pepper spray, white smoke and some rubber bullets into the crowds. . . . The folks that organized Thursday’s unauthorized march, the G-20 Resistance Group, is encouraging members to spend the morning, before the march, to take unspecified actions against local offices of corporations deemed evil.”

No arrests like these at the Tea Parties, either. Until we see scenes like this, I don’t want to hear yammering about the violence inherent in the Tea Party movement.
