ABSTRACT
A couple of years ago, one of us presented a talk about missingchildren at a local college. Following the talk, a member of the audience came up to the podium to chat. “It’s really horrible,” she said. “I don’t let my kids leave my sight for a minute. Not for a minute. Not for a single minute.” Her voice was strident. Her concern was palpable. It was concern not just for her children, but also for the world they were growing up in. It is a concern shared by many.
