Correspondent Kaj Larsen investigates the alarming rise in the number of soldiers who have been traumatized by war and are now accused of bringing the violence home. Of the more than 2 million men and women who have served in the recent wars in Iraq and Afghanistan, as many as a third of them may now have post-traumatic stress disorder, or PTSD. A growing number of these vets are being charged with violent crimes, and Kaj travels to prisons and mental health facilities in Arizona, Colorado and Oregon to hear their stories.
