Here's another site:

http://www.missingkids.com/ - The National Center for Missing & Exploited Children lists sites for each state that list sex offenders

KEEP IN MIND that not all sex offenders are listed (those who aren't registered or ever been caught), and just because someone's labeled a sex offender, doesn't mean they did something severe or deserve to be labeled a sex offender.

For instance, recently, on our local news, two boys were facing legal trouble for slapping girls on the butts in school. Some girls were okay with it, some not. One girl stated, "It's like a handshake we do." One of the boys said, "Lots of kids at school do that." I don't know what the latest is on this story, and I definitely think the boys deserve a punishment and a good lesson about sexual harassment, but one of the possible consequences they could face at the time of the story was having to register as sex offenders for the rest of their lives. I just don't see them on the same level as a rapist, whether we're talking about adults or children. What they do in the future may be something else entirely, but for now, I don't think they deserve the "sex offender" label for what they did.
