I believe the idea of gun controls is to use them as methods to try preventing the criminals from getting the guns, not to take guns away from non-criminals or prevent them from getting guns. There is a chain of handling from the manufacturer to the seller to the customer. Somehow there has to be a way to stop the guns from getting to the wrong people so security and checks have to be in place for that to even try to happen. The supply chain is full of holes that need to be plugged. I'm sure all the think tanks working on this problem would love to hear from you if you have any viable ideas they haven't thought of already.
