Some sex offenders are successfully suing, arguing they have a right to go on social networking sites like Facebook.

FOX News Radio's Jane Metzler reports:

Registered sex offenders, suing to use social networking sites like Facebook, already winning legal challenges in Nebraska and Louisiana, with other lawsuits pending.  At issue: their First Amendment right to free speech versus the protection of children.

A number of states, enacting bans to keep pedophiles from preying on kids in chat rooms and on social networks.  The ACLU, insisting the internet is now essential for communication and all should have access, including sex offenders.

Critics call it a place for them to find new victims, saying sex offenders can still use the phone or send a letter.
