You may remember a few days ago a story of an Israeli military officer that struck a foreign (Danish?) protester with his rifle.
After watching the video, I didn't see that the officer used excessive force. First of all, the blow was with the side of the rifle and was more of a forceful push. Second, it appeared to be justified given that the protesters were ordered back, but failed to comply. The soldier was a heck of lot nicer than a cop would have been under the same circumstance.
Anyway, the protesters revealed their true colors, scrawling a Nazi swastika on the wall of a detention room.
