The issue of security versus privacy is under the spotlight again as attorney's general in the US are demanding that MySpace give them the names and addresses of thousands of people who have been previously convicted and who could now be using the social networking site to contact children. 

It's a prickly issue: MySpace has come under fire for not doing more to protect children using the site, and it's known that some adult abusers do use it to contact children, usually posing as children or teenagers themselves.
The attorneys general of Georgia, Idaho, North Carolina, Ohio, Pennsylvania, Mississippi and New Hampshire all signed a letter written the the attorney general of Connecticut, demanding that News Corp, which runs the site, hand over the information.
Apparently, news of the large number of convicted sex offendors using the site was discovered during an unnamed company's investigation.
