I don't know what the statistics are as far as where you would find the larger concentration of what kind of firearms. In other words, are there more 9mm semi-auto handguns in the cities than in the country? I'd venture a guess and say that it was so. Then I'd also venture a guess and suggest that, not unlike cars, who taught the one with the gun in his hand how to use it?
When I was 10 I was in charge of cleaning all the guns in the house. I had solvents, rags and rods and could take apart all of the shotguns, rifles and pistols and clean and put them back together -safely. Of course, my father spent a good bit of time training me on how to do this safely - and why I was taking care of these tools. I was also a darn good marksman and still am.
As an adult, I have coached, taught and trained hundreds of young people how to do the same - as well as coaching two young men to the level of Olympic development team. My son and several of his friends just competed in San Antonio winning a 1st, 2nd, 3rd, and 4th place in different shotgun sports - in their first year. Tens of thousands of rounds of practice have been fired. In one year my son shot over 20,000 targets of practice, and he was one of 30 kids I coached that year. We never even came close to a problem from an accident. We REALLY never have since come close to one of these kids taking his 9 and bustin a cap on a store owner. So it must be the guns, right?
When we finally realize we can't continue with all the politically correct garbage and can once again hold the parents of children responsible for the child's actions (how it was when I was a kid), momas and daddys will all the sudden be a little more interested in poppin out those babies. If daddy isn't there to teach the daughter to drive - how is she going to ever learn how? Then how is she going to teach her daughter when her "husband" is gone too. It is the very same problem with "guns."
Blaming the gun is blinding yourself to responsibility for one's actions, period.
