"That's such a sneaky childish school playground tactic to deliberately wind up other kids
to the point of such anger they strike the first blow..

"So let's go out obstructing busy traffic and deliberately provoking ordinary folks into acts of road rage..."

This is a flawed argument. On the whole, the aggressors are not "ordinary folks." They're the police, the agents of the state, who generally act under orders. One more thing: a bunch of protesters sitting on tarmac is not putting lives in danger. They are not carrying guns or swords or tasers and they are not driving tons of wheeled metal at high speed. So who is really, if anyone, putting lives in danger in those demos? Let's avoid the Daily Mailist arguments, eh?
