State of Sex Offenders

Lisa Ling explores the challenges of living life on a list of registered sex offenders as she meets with ex-cons in Florida. "They're America's pariahs, pushed into the shadows," she says. Or, as one man living in a swampy campground with other offenders calls it, "the leper colony." Ling also meets a real-estate agent who finds more substantial housing for offenders who can afford it; and follows authorities as they arrest an ex-con accused of failing to register an address change.
