I started hearing from families who had missing members, many of them young kids on our campus, and they all would describe the same sorts of things. A sudden change of personality, a new way of talking... and then they would disappear. And bingo, it was the same sort of thing as with the Korean War prisoners, the same sort of thought-reform and social controls. You find it again and again, any time people feel vulnerable. There are always sharpies around who want to hornswoggle people.
