Ukraine: Muslim girl stoned to death for participating in beauty contest

The fact that this was an extrajudicial killing doesn't let Sharia off the hook. The fact that stoning is prescribed for adultery (as often as apologists might also try to deny it for non-Muslim consumption), where the murderers in this case apparently decided for themselves her actions were tantamount to adultery, doesn't let Sharia off the hook, either.
No, the simple fact that this punishment exists in Islamic law, and Muhammad himself participated in it, means Sharia's inherent defects where human rights are concerned have a direct bearing on this case. So does the broader sense that originates in Qur'an 4:34 that violence is an acceptable recourse against "disobedient" women.
The murderers' consciences were informed by these ideas, hence the lack of regret expressed below. "Muslim girl, 19, 'stoned to death after taking taking part in beauty contest'," by Will Stewart for the Daily Mail, May 30 (thanks to Ian):

A teenage Muslim girl was stoned to death under 'Sharia law' after taking part in a beauty contest in Ukraine.

Katya Koren, 19, was found dead in a village in the Crimea region near her home.

Friends said she liked wearing fashionable clothes and had come seventh in a beauty contest. Her battered body was buried in a forest and was found a week after she disappeared.

Police have opened a murder probe and are investigating claims that three Muslim youths killed her claiming her death was justified under Islam.

One of the three - named as 16-year-old Bihal Gaziev - is under arrest and told police she had 'violated the laws of Sharia'.

Gaziev said he had no regrets about her death because she had violated the laws of Islam.
