It's not the aims, but the means that is wrong. I feel the same about many things on this. Violence and intimidation is the act of the bully, down through history.
There is no difference between this group of wrong headed people who made the futile gesture of vandalising Goodwin's house, and the Angry Brigade. They both hide their criminal acts under a the disguise of anonymity.
They can dignify their actions by calling themselves something crusading, but it still remains a fact, that they broke the law, and Fred Goodwin didn't.
I'm not saying I agree with his actions, or that of his ex employers, but neither to I agree with cowards who hide in the night, and commit crimes.
