At the end of the day the "victim" was a weapons smuggler whose weapons were were used to kill and target civilians in Israel. So who cares if he is dead? At this point in time the only two people under arrest are in fact Palestinians with links to Fatah. Nothing is known about the suspects and they may have covered their trail so well they will never be caught, and then were just left with idle speculation about the suspects. Oh Yea! that and two Palestinians. Whoops!
