Maybe revolutionary violence should be removed from these large protests and put to more constructive use. At these events we are always at the disadvantage in arms, preparedness, and ability to make effective statements to the surrounding community. I think the anger is justified, and i think the police, the imf, and all the other oppressive factors of this society will have to be engaged if we're truly serious about bringing dramatic change. "Diversity of tactics" is going to have to start meening alot more to us would-be revolutionaries if we want to bring down these powerful systems, because our tactics can only be but so diverse in the protest context. Yeah it sucks that a worker was hit by a brick, but what we should be talking about here is not striking violence from our movement, but rather exploring more effective targets and uses of the violence.
