When Roni Yechiyeh was murdered on Wednesday, the closest one could find to a picture of his body was this one, made by an Israeli photographer for Reuters:
Shoes lie beside the body of an Israeli killed after a rocket attack in the southern town of Sderot February 27, 2008.
The picture is meant to evoke sadness and loss. To show his face would be demeaning and painful to his family. With few exceptions, this is how Israeli victims are shown to the world by Israelis themselves.
On the other hand, the Arab press- and Arab photographers for the wire services - revel in showing bloody dead bodies. When a baby dies, his picture gets plastered on front pages (like this one in Ma'an today, I'm not going to reproduce it here.) There is no indication that the families of the victims are upset by this - it is as if a child being killed is cause for celebration, because it can be used as ammunition against Israel in the war of public relations.
The glee at which PalArab deaths are embraced can be seen from this rally, which in a normal culture would be characterized as child abuse:
In short, Palestinian Arabs celebrate both Jewish and Arab civilian deaths, while Israelis mourn them. Death, which is described countless times by Palestinian Arabs themselves as reasons for celebration, is also a major propaganda victory.
And those PR victories, milked for all they are worth and more, give them all the more reason to celebrate.
