Arabs Celebrating?

I read some news. That osama was gone. Also, that arabs were celebrating what was going on. Not what I see. There are in my city many groups. White Christians were celebrating with obvious joy. Latinos, most of which are Catholic, were honking horns of their cars. However, on the arab side the mood was very grim. In front of an arab coffee shop were no men. A woman cleaning the floor was weeping. Her husband looked very sad like a man who lost his only son.
