You have a point. To keep him from having a gun you would need to take all guns away from all people. But to do that you need a big bunch of guys with guns and to kill lots and lots of people as you go about taking them away. Many many, including me, would have to die. I don't like the idea of dying but I would rather die than live in a gun free wonderland like Germany was during the Holocaust, or Rwanda, Cambodia, China, Russia, or that wonder of all wonders present day Mexico. A gun free heaven if there ever was one.
