The number of crimes that would be prevented if everyone had a gun would not be nearly as high as the number of new crimes that would be generated. Think of the number of people every day that get depressed about their lives. Some of them will get drunk or find some other way to vent their frustrations. Do we honestly want these people to have a gun in their hand? I can't think of a worse world to live in. And that's just a specific example. At the end of the day, more guns in peoples' hands=more chances to kill people. Also, deepest thoughts go out to the families affected by today's horrific tragedy.
