First of all stoning is very much a traditional Jewish killing as well - let's quote the old testament... "And Joshua said, Why hast thou troubled us? the Lord shall trouble thee this day. And all Israel stoned him with stones, and burned them with fire, after they had stoned them with stones." (Joshua 7:25) And there are numerous other examples. Anyway: no civilians throwing rocks do not justify the use of firearms (certainly not in the very lethal way that the IDF likes to use them), except possibly under very special circumstances. However "traditional" stoning may be as a means of execution has little bearing on the threat rocks pose to a military unit - you do realize that victims of execution by stoning very rarely were part of a large group of people that could move around and use anti-riot means of crowd control to defend themselves, right? Yeah it was actually some poor sod lying tied on the ground, a slightly easier target one might think... When the IDF uses lethal force to quell a stone-throwing crowd it is a testament to its unsuitability for the role it is being deployed for. That sort of task should be assigned to people who are trained to handle civilian crowds, not by people who are trained to kill enemy soldiers.
