I don't have any problem with this. Their victims had rights too. If someone abuses the rights they had and completely ignores the rights of their victims, they have shown that they do not respect the entire system of rights in the first place. They should forfeit what they have abused and ignored and/or be removed from the society they **** on.I believe the 2nd Amendment says shall not be infringed.
If a person is a murderer, or so violent that they should not own a firearm they should be hung by the neck until dead or put to hard labor for the rest of their lives. As for those who do serve their full sentence in prison once out they should have their rights restores.
I do not believe in parole system at all.
