Well, I strongly object to superpanda for bringing in shariat issue.
This matter is purely a social matter of Afghanistan.
and unforturnately the perperator and the victim are muslim, it doesnot mean that the principles of islam are false.
For sure some societies misuse the Sharia and use it for their interests, its the same happened in Afghanistan and poor woman has to suffer. whereas the culprit should have been hanged for his heinous act.
