Yes, there are such things. I honestly don't know enough about Arab society to say how honor killings of Arab women are regarded by various groups, and I'm willing to assume that most Arabs regard them with as much horror as the rest of us do. Still, you can't change the fact that honor killings do exist in Arab societies, while they don't exist in other societies. The case of the Arabs in Israel is interesting, since they're a minority, and the majority society around them totally condemns the practice, which means that there is no chance that the police and courts might be convinced not to investigate, as - you'll pardon my saying - could conceivably be the case in, say, Saudi Arabia or Sudan. Minority or not, there are Arab Israeli men willing to murder their sisters or cousins if they feel the sisters have defiled their honor.
The honor of the men, mind you. The way they see it, they're the victims. That's the mechanism.
The most famous case in recent years has been the serial murder of the women of the Abu Ghanem (pronounced Abu-Ranem, with a deep R) clan of the violent neighborhood of Jouarish, in Ramle (not Ramallah. Ramle is in Israel, about ten minutes from the Ben Gurion airport). After the eighth murder, in January this year, some of the women of the family broke the rules, went to the police, and told everything they know. Which means that a mother and her daughters and nieces testified to put the son/brother/cousin into jail for the next 20-25 years. And then their fears overcame some of them, and they began backtracking; one of them hasn't been seen for quite a while and may already be dead. Yesterday, however, the mother and a cousin testified before the courts. It is now irrevocable.
Yet to be seen is if this case will manage to prove a significant turning point in eradicating the entire phenomenon among Israel's Arabs, or merely an isolated case, or perhaps even less than that. Clearly it's an extremely dramatic case, about love, hate, tradition vs. law, fear, violence, heroism. No doubt it's only a matter of time before Hollywood makes a major film out of it.
No? Hollywood won't?
