I dont see a problem with owning guns. Its just taken too lightly in the states. To get a gun where im at, you need to get certified - theoretical, physical and psychological tests are done. And no one starts pissing about personal freedoms if they fail these tests. I think you also need to be member of a shooting club. Point is, you need to demonstrate your ability to handle a weapon responsibly. Im not one to confuse correlation with causation but… you dont see many stories of shootings here.
I wouldn’t look at it from that perspective. Similar situation with driving licenses, which require first aid training, 20+ hours of driving lessons with an instructor, theory lessons, testing, and costly things of that nature. If you want a gun and are fit to own one, you will not have a problem doing so, no matter your class.
