Today was awesome for anyone who likes to see proper angry protest in a progressive cause. Aaron Porter might think those who smashed windows were "despicable", but as someone who's been on one too many protests where you see too many of the usual faces, a demo like this says something that 'peaceful' (let yourself get kettled by the cops and don't say so much as a bad word about it) protests don't quite so well: we're really angry. I think people in power tend to get more sleepless nights about angry protest than peaceful protest.
Always good to see a bit of people power and a progressive cause taking control of the streets, anyway. And if you wanted a demo without dickheads you might as well wish for a police force full of paragons of virtue. Just accept that people REALLY don't like Condem policies, guys.
Not that it needs stating, but just for the record: I don't think violence is to be welcomed, but if you're pushing through policies that hurt people, people can't always be relied on to wait for deliverence from a Mediator. Besides, as a revolutionary I tend to think that only the co-ordinated power of the working class can overthrow the class system itself and bring an end to the conflict inherent in class societies - and I don't expect the bourgeoisie to give up easily.
Not that I was on a demo, mind. I work for a living, me.
