Soldier's alleged Kandahar killing spree: Were warning signs missed?
Whether it was a psychotic break or underlying mental illness that led a United States Army soldier to allegedly massacre 16 Afghan civilians -- including women and children -- is still unclear. But as military investigators reportedly interrogate the 38-year-old staff sergeant they say they believe to be behind the Sunday morning killing spree, psychological experts said such actions are generally preceded by strong signals that something is wrong -- signals that, in this case, may have been missed or gone unreported. Whether any of these warning signs were present before the alleged mass killing is as yet unknown. But Dr. Bengt Arnetz, professor of occupational and environmental medicine at Wayne State University, said that even if these signals were present, the current system used by the military is woefully inadequate at detecting them. "All the systems have never been evaluated," said Arnetz, whose research focuses on the effects of stress on the psychological well-being of police, first responders and soldiers. "I think that they're very, very bad at monitoring people close to the breaking point. We don't have good surveillance tools."
