The Fourth Circuit court has ruled on a case in North Carolina. The ruling says that if Open Carry is legal, then carrying openly does not constitute Reasonable Articulable Suspicion for the police to stop you.
This is what Casad (the unpublished case here in Washington) found, but this is the first time that I know of that a Federal Circuit court has ruled the same. Keep in mind that this doesn't apply outside the Fourth Circuit, but could be used as precedent. If another court rules otherwise, that sets up for a SCOTUS battle.

I don't know if this is the right place to post this or not, but just because my brother framed me of harassment and stalking and I was convicted when I did none of the things he said I did, they revoked my handgun carry permit. Upon much more research, the 2nd amendment that we all are under says that I have a right to own and bare arms! But now the state of Tennessee has made laws to make sure that I can't carry my gun with me concealed or open without a permit. This sucks and I am searching for ways that I can do this without leaving Tennessee. States like Arizona, don't even require a permit, if you have a legal drivers license, you can carry.
