"Our attack is violent... Our violence is organised. The question is not whether the revolution will be violent. Organised militant struggle and organised terrorism go side by side. These are the tactics of the revolutionary class movement. Where two or three revolutionaries use organised violence to attack the class system... there is the Angry Brigade. Revolutionaries all over England are already using the name to publicise their attacks on the system. No revolution was ever won without violence. Just as the structures and programmes of a new revolutionary society must be incorporated into every organised base at every point in the struggle, so must organised violence accompany every point of the struggle until, armed the revolutionary working class overthrows the capitalist system."
