If you’re in the UK you can catch an episode of Louis Theroux LA Stories titled “Among the Sex Offenders”.
Documentary. Louis Theroux spends time in the twilight world of Los Angeles’ paroled sex offenders, who live under force of tough regulations
As a non UK resident I cannot watch it but if you happen to catch it we’d love to hear your opinions on it. It’ll only be available online for a couple of days if you’re interested.
