Have to say I think it's good to remind our politicians once in a while that sometimes people can get so pissed off they want to smash shit up. Politicians don't really care about peaceful protest but they do give a shit about civil disobedience, civil disorder and/or revolution. I think it's the only thing that sets a line that warns the government not to cross it. If people are just moaning or walking through the streets calmly, it sends the message that you're ok and could probably push a bit further.
