If you have not realised by now that nonviolent disruption is society’s best defence against injustice – its best warning system – you’re not paying attention.

Reading this again, I have to admit I don't fully agree with this quote, in the sense that I couldn't claim that "nonviolent disruption is society’s best defence against injustice". I could easily say something like its a warning system, but definately not the "best".

Still, I do believe that non-violent disruption can be a useful part of the "tool-box" for change in a society, and sometimes a stepping-stone.
