Is that site 'official' or just a 'fan site'?
The CHRIS site isn't just for Venables, it lists all known paedophiles/persons connected of crimes against children. Anyone can submit a name but details are checked with police and other agencies before listing to prevent abuse from "friends" or disgruntled ex's
The site isn't just a "list" it also has links for children in trouble, it gives advice to parents on how to spot the signs that their child might be at risk. There are a lot of cases on there, comments on certain Judges and their "unique" way of dealing with offenders, some of this can make for interesting and informative reading.
