By the way, there are many states that give all rights back to felons, except 2nd amendment, when released from jail/prison. Why should the 2nd be treated any different? Because guns can be dangerous? Sorry, but they are not barred from archery equipment; baseball bats; golf clubs; etc.
So if I understand you correctly, a convicted murderer should be allowed to carry a firearm after release? Given that logic, I would suggest it would be alright to permit a convicted child molester to again teach school upon his release.
