That barrier is there to stop terrorists getting into Israel, remember the days before we had the barrier when people used to get onto busses and blow themselves up. Hamas resorted to rockets because suicide bombing was no longer as easy as it was largely thanks to the barrier. If somebody was trying to climb over it then its doubtful their plans were entirely honest, if you have nothing to hide you enter via the border crossings. The soldiers saw a man trying to climb over the barrier so they did their job and shot him. Its called defending the borders so those soldiers have absolutely nothing to be ashamed of and they can go home and forget all about it, just another incident.
