Disillusioned kid summed it up quite well in his posts about the event:

"During the speeches, a “checkpoint” was set up to try and convey the realities of Palestinian life. Participants stood in line waiting to have their papers checked by soldiers. Somehow I suspect that in reality Palestinians don’t have to stop the wall blowing down in the wind, although as a piece of street theatre it seemed quite effective."
