the IDF soldiers didn't know what to expect from a crowd trying to cross the border. Last year there was a firing incident initiated by Lebanese border guards, in 2006 it was Hezbollah that violated the border by abducting Israeli soldiers from Israeli soil. This time the IDF reasoned that you better be safe than sorry, which I can understand. The deaths of this kind of 'demonstrators' leaves me cold, I couldn't care less. I support the IDF in this matter.
