Don't get raped in Saudi Arabia

In Saudi Arabia, a 19 year old girl was traveling in a car with a male friend. They were kidnapped and raped by seven men. So, of course, the natural result is that the female victim would be prosecuted and sentenced to six months in prison and 200 lashes. After all, she was in the company of a male she was not related to. I mean, come on! Who wouldn't condemn this little harlot for the brazen act of riding in a car with a boy? There's probably a queue forming of people who want to wield the whip. I'm surprised the men who raped them weren't given medals for honorably punishing the tramp. She obviously was asking for it, being with a non-related man.

I don't like to generalise a whole society, but there has got to be something wrong with the water over there. I'd hate to visit the mind of the person to whom this makes sense.

Sarcasm aside, my question is, why do societies continue to punish women because the men can't be trusted to keep their dick in their pants?
