An Israeli won't try to break to cross the border with Lebanon either, cause he knows that there's a lot of risks he'll get shot at. Same goes for this situation, they knew what could happen. And btw, the IDF has a whole procedure before they can open fire at people. Soldiers even have to learn how to say the procedure in arab. First they have to tell them to stop (a few times), If they don't listen the IDF is allowed to fire in the air, if still no reaction, they have to shoot around them, if they still don't listen (and believe me, at that point if they don't listen, they're not innocent), the IDF is allowed to shoot at them. So if they were fired at, they weren't up to anything good. And this wounded girl, I even wonder if she even got wounded by Israeli gunfire, cause pallywood is still very active. Or off course, she was at the wrong place, at the wrong time.
