That would be the case in most of the situations, but not in the Palestinian-Israeli struggle. The two football players being about to throw a bomb, is very unlikely, but it is completely irrelevant. The Israeli forces have never needed any cause to shoot Palestinians. Similarly, and for example, a soldier in the Lebanese army shot an Israeli soldier who was just passing by the border a couple of months ago. Thousands and thousands of unarmed civilians, mostly from the side of the Arabs, have already been killed in the ongoing conflict. So while this incident is sad, it is by no means shocking or any different from similar incidents that occur on a daily basis.
