NOBODY follows a train of thought to insane consistency like a libertarian psycho. “Gun control is bad, so convicted murderers should be able to possess sub machineguns in prison.” That’s a libertarian for you.
Dr. NO brains... NO libertarian I ever met has EVER said that convicted criminals should have access to firearms during their incarceration. Ever. You need to watch what you’re smoking. What HAS been said is that when the criminal’s penalty is paid, his rights, including the right to own firearms, should be restored. His sentence should be served in full and, if he’s dangerous, there should be no plea bargains and NO PAROLE.
