Yeah, it's a major shock to say the least. This incident sparked very heated debate, probably because Israelis know that everything is rotten inside. I hope that lot of them were forced to face this realization and to decide to do something about it.
I don't watch TV or listen to radio beside music, but I heard from someone else that one of the police officers who was in the area and approached the body, said on the radio that media has overreacted. He said that the biker was crushed by the truck and his guts were all over the road (something that we didn't see in the video) and that it was obvious to everyone who passed by that this man was beyond hope.
I have no idea if it is true, and even if it is true - personally I find nothing wrong with showing Israelis ugly nature in such a harsh way. The more, the merrier.
Maybe they will have a very good look at themselves.
