Journalist Alex Kotlowitz spent a summer in Chicago chronicling people whose lives were changed or lost due to gun violence. He likens the trauma of living with gun violence to the PTSD some veterans experience. "Once you've had one act of violence around you it's hard to escape it, and so I just wanted to get at how the violence gets in people's bones," he says. His book is 'An American Summer.'
