That entire thing disgusts me. I remember a few stories of ~19 year old guys with ~16 year girlfriends and the 19 year old was either beaten or killed by idiots who saw them on the sex offender registry. Other cases were less severe with such people being ostracized by their community. I don't believe public sex offender registries should exist period, but if they have to, people with crimes like public urination or having a hardly underage girlfriend should not be on the list.
I am not really up on sex offender registries and all the crimes that these individuals have to register for, but how in the world is urinating in public even a sex related crime, unless the individual was paticipating in "water sports" with their partner at the time?
Some states do include an age difference in their statutory laws and 16 is the most common age of consent in the US and is the age of consent outlined in the UCMJ for military members. If you are convicted of a statutory offence in one state and move to another, it should only be made public on the list in the new state if the conviction would of still met statutory laws in that state. Crimes like solicitation and many other "sex" crimes should not be on a list.
The only people who should be put on a sex offender list are those who meet statutory requirements (with a sutible age difference clause) but the underage person has already developed sexual attributes. Ok, that probably just confused the hell of of some people. Basically, I believe that if you commit forcable rape/sodomy, molest children who have not "budded" or other heinious sexual crimes, then you should be convicted, subjected to chemical interogation to confirm guilt, then taken out back, put on your knees and receive a double tap from .22 into the back of your skull. No need for a list of them then.
The government overall is still trying to get a grip on the whole internet thing. Why it is taking them so long, /shrug, I have no idea. It is not overly difficult. All of us, and probably anyone who has done a search on the internet have encountered offensive pop-ups and sights that are listed as one thing in the search but have been taken over by someone else. As I accidently found out one time, if you want to search for sex related sites, don't search for sex related sites, search for children sites. Pokemon, Barney, Dora the explorer searches yield far more porn results than searching for "porn". It is not hard to get a count of how many times someone took a certain link, a couple of hits is probably a mistake and you shouldn't be held responsible for it, but if you went back to the same link 100s of times, you are intentionally viewing the material and if that material is child porn, to bad, too sad, enjoy the sexual comforts provided by your cell mate in prison. If you purposely posses, distribute or produce child porn, then if the state is short of bullets, I will be more than happy to go to Walmart and buy them some more.
