No they weren’t. I spoke to a Jewish woman about this and the video pretty much gets it. It was tension between traditional Jews, who wanted to keep things as was or go through the proper channels to enlarge the building and the Messianics who wanted to bypass the city ordinances. The young men in question decided by hook and crook that they were going to fill the order by the notable rabbi to expand the building.
What about the pedo rumor? They pulled out mattresses and baby chairs.
