This has been proved by Japan where a thorough and careful background check is required of anyone wanting to own a gun. Japan had just three gun deaths last year! The United States had over 30,000. Now, it is true that their background check is thorough, careful and exhaustive, and I expect that maybe 50 percent of Americans would fail it. But to the tens of thousands who would not have to suffer death and the hundreds of thousands of their relatives, friends and loved ones who would not have to suffer the agonies of their loss, I am certain that it would be worth it.
