I guess we're saying the same thing. It's not the number of firearms available, but rather the attitude of the people that put their hands on them. You and your friends wouldn't have thought of taking a pistol to that imaginary breakin, much less actually pulling the trigger on another human being.. Unfortunately, many people (not just the young) seem numb to the concept of killing someone being wrong. I agree that's it's lack of parenting, but also think it's repeated exposure as well.
