The chronic culture of violence in the North Caucasus shows few signs of letting up. In July, Natalia Estemirova, a leading human rights advocate in Chechnya, was kidnapped and murdered. Less than a month later, two other activists, Zarema Sadulayeva and her husband, Alik Dzhabrailov, were killed. A new report from Human Rights Watch offers little comfort to those seeking justice for these and other crimes.
