Let me try to answer this a piece at a time.

"Pardon my confusion, but if you are not currently required to register, how does SORNA and the 7 day grace period after crossing state lines remotely apply to you? And what would happen on the 8th day? You would technically be required to go to the police station where ever you are and tell them you want to register? With what kind of information? Aren't you completely out of the system?"

Unlike marriages, business contracts and other "civil" measures, state's do not have to follow the registration requirements of another state. I am not on the registry in my home state. But, if I moved to another state I might have to register according to their rules. States with lifetime requirements such as California, Florida, Texas, etc. would require me to register.
The 7days in SORNA is for those currently registered or Federal and military. I was Federal. Nothing would happen on the 8th day unless they knew I was there and chose to file Federal charges. The Feds only seem to after people that have moved and not registered, not visitors.
Yes, technically I would be required to go to the police station and register. No, you are never truley out of the system.

"What if you got an expungement / dismissal? You would technically be not convicted of anything? And be the same as any other citizen, without any kind of requirement whatsoever?"

Full expungement or pardon would make registration moot. There is no conviction.

"Which states require registration if you were EVER convicted? There was another user on here talking about that and that was bewildering to me, too. What is the point of getting off if you still have to follow all the rules?"

The states that require registration if you were ever convicted, that I know of, are California, Florida and Nevada. There may be more. The point is, you have most of your life back if you stay put!!

This is just bizarre...

Yes it is!!!

Thank you for your explanation. I still do not quite 'get' it.... to think that 'we' have no needs more pressing than playing these games... what a pathetic place this country has become.

'Staying put' was the cornerstone of East Germany. I object! Land of the Free and Home of the Brave my arse.

So if someone were just to for a visit to see family in Florida [shiver and shake] or take a weekend at the beach, can he slip in and out as long as it's only for a few days?

October,
The simple answer is yes. The complicated answer is; have someone else drive, traffic stops; do not use a credit card in your name, financial record; do stay in one spot for more than their 3 day trigger, 3 day registration demand; just be careful, stupid is the enemy.
If you are there for 3 days or less in a year, you are within the law if you do not register. They might hassle you if found out, but can't file charges that would stick. Even at 4 or 5 days, it would take them more than a week to find you unless someone reports you.
Low profile all the way.

I think everyone should go to http://www.opencongress.org/bill/hr3253-112/show and at least vote No on the support of this bill. Maybe it will help.

I find it interesting that there are no co-sponsors for this Bill. Kind of tells me it has no importance to anyone else.

TX for your efforts CRich!

Lilly,
That is the reason I am here. If I know the answer to a question, or have a valid comment, it is my duty to pass it along. We need to educate ourselves before we can educate someone else.
Once more, no thanks are necessary.

Voted!
