I see the issue, debates can propose hypothetical situations. So hypothetically a gun can jump off a shelf, load itself, hop down the street and shoot someone? Figure it out, there ARE people out there who despite the means will and WANT to do people harm. Denying they exist is no better than burying your head in the sand. Simply put, "If you want to try to outrun a bad person with a gun (because they won't give theirs up) be my guest. I'll pray a nice person who is carrying a gun is willing to defend your life. In the mean time if you want to discourage crimes with firearms, why not work for tougher justice for those who would commit crimes WITH a gun?
