In the US, like the UK, sex offenders have to register with the police. But in the Land Of The Free their locations aren't kept hidden from the public.
4,400 registered sex offenders were evacuated from the areas hit by Hurricane Katrina.
But only 92 have been re-registered.
In other news, three evacuees have been charged with murdering an elderly church worker who offered them work. Nice people.
