I feel that "nonviolence" is very loosely used by the group to refer to "no violence" as opposed to being a "nonviolent movement". I think there needs to be a committee that specifically discusses how nonviolence principles can shape the movement - Gene Sharp's book has been a good guide for our Egyptian friends - i am sure there was a focussed effort to read, understand and strategize based on it.
Nonviolence is as much about strategy as it is about being peaceful and not being violent. I think a focussed effort is needed in doing a deep evaluation of how nonviolence principles can determine the course of action.
On a side note:
I also think we need to start with the end in mind - what does accomplishment look like? And then determine how we can apply nonviolent techniques to move towards that. This will give us tangible exit criteria, and a yardstick for those involved in the movement to know where we are, what is working and not working, and how we can adjust course to get to the end goal. I know this is easier said than done, but again, there needs to be a focussed effort towards this - to make sure that the occupation is not a wasted effort.
