Even if the photo is undoctored, it's obviously a staged event. If someone was shooting at Israeli's, the crowd wouldn't be cringing towards the shooter but rather would be anxiously looking towards the target.
Bingo. I did a search of this fauxtographer and he's up to his filthy neck with the terrorists. He specialty seems to be propaganda, (aka "action") photos. For instance, several years ago he stood there and took pictures while his friends shot an old man in the head for cooperating with Israel. Recently LGF had something on him. Photoshopped or not, this guy is nothing more than a terrorist POS.
