As far as I know, they don't sell guns behind prison walls, so he would not have been allowed to purchase one if he was kept where he deserved to be.
Obviously the laws already already restricting him from purchasing, owning, and carrying a firearm did not work, so sure, let's just make MORE laws, that people like him can keep breaking.
I'm sure once they realize they're breaking a certain number of them, which is obviously MORE than we have now, maybe 20? or 30?, it will make them stop and rethink their decision. We just have to make that number higher!
Hate to break it to ya, but criminals don't buy their guns at gun shows, even from FTF sellers. There's too many police around. They generally avoid cops as much as possible.
Besides, criminals prefer cheap weapons. I don't think you're going to see one purchase a M1 Garand from a guy carrying it around with a 'for sale' sign on it.
They buy them on street corners from other criminals, or have friends and relatives buy them for them as straw purchases. (add another broken law to the list!)
Even if you made FTF sales illegal, they would still do it, and would still get guns, because, oh yeha.. CRIMINALS DO NOT OBEY LAWS.
And with that, I'm done in this thread.
