This statement says it all as to WHY they were there as in the last paragraph of the transcript. Document the event, they KNEW.
Indeed, if they actually did so, I would support stoning them to death. However, all we have here is a report from a woman ("Maria, who asked us not to use her last name") watching them from a distance through binoculars, saying it looked like they were "happy", which is not as straightforward as the TV footage of dancing Arabs we were treated to.
Perhaps we should have a look at the video they shot. That would provide a very clear idea of what they were saying and how they were behaving. But then, we might risk have our opinions clouded by actual facts, which are conspicuously hard to find in this article.
