I can't shoot an automatic handgun with any accuracy at all. I'm better with a revolver, but in all honesty, I'm very aware that in all likelihood, any handgun would be taken from me and used against me. I try not to be delusional most of the time.
But yes, Prohibition is a good example of what bans do. More people will own guns because they become attractive as forbidden fruit. Background checks and properly supervised sales will ensure that people who want guns and are not a risk to the populace at large can own them.
My dad loved guns, and always had them. He kept them in a gun safe, he shot mostly at a range, and he was one of the range members who volunteered to teach gun safety to Scouts and other groups. I went to the range with him, and enjoyed it thoroughly. My objection to guns is the idiot boy-child holding it sideways like a freaking rap video, who couldn't hit the broad side of a skyscraper with a freaking howitzer. Personally, I say we take all these young idiots, put them in a locked arena, and let natural selection do its thing.
