“Violent criminals should not be allowed to continue to terrorize society.”.........It is really odd that a criminal can be deemed violent enough to not be allowed to legally own a gun, but is not deemed violent enough to still be in prison.”
There is no perfect application of our 2nd amendment rights. Sometimes what is fair, what is just requires a compromise. It is not unreasonable that we consider the length of prison as a limited time, and still think the commission of a certain crime ranks as qualifying for other restrictions that may still apply after the prison term is completed. Maybe further compromise would serve justice better by making the other restrictions apply only for certain time limits as well, and not permanent. It would probably be added that no other felony occurred during that additional time limit. That would make it like a “probationary” period where the formerly convicted person is demonstrating their abandonment of the behavior that got them into trouble; after which any additional restrictions would no longer apply.
