Right! I expect to learn that the shooter is a Palestinian who has been trained in sniping.
He knows that a single shot is very difficult to locate by sound and a .223 is very unlikely to let out a puff of smoke unless it is fired close to dirt or dust.
And he knows to pick a variety of targets that will scare hell out of people.
Does anyone else remember a sniping incident that took place in Israel a few months ago? One Palestininan sniper killed several Israeli soldiers at a checkpoint over a fairly protracted period of time. I'm afraid I can't recall all of the details...can anyone else?
