I read about this video on MJ Rosenberg's site, then at Mairav Zonszein's. It is apparently from Palestinian television, but picked up by B'Tselem: the group of bicyclists demonstrating for freedom of movement on a Jewish road in the Jordan Valley last Saturday.
You can see Lt. Col. Shalom Eisner's belligerent face at :09, as he warns a Palestinian television reporter. His assaults begin at 1:50, with an attack on a woman in a white blouse. There are two more assaults in quick succession, at about 2:00: the first the famous one on the Danish cyclist, then an overhand attack using the gun. Then two more at 2:22. The lieutenant colonel is out of control. What will arouse people to look on the new face of Israel?
