Not sure how you get there from the hundreds of millions of guns and millions of law abiding gun owners out there?
We are a very big country with wide open spaces and many a good reason to own guns. Some people don't have the best of motives.
Let's just understand one thing: People who don't live here don't (maybe can't?) understand and I'm not going to change that here.
You'd get there by simply comparing the statistics and if you can't see the direct correlation between the number of shooting incidents and the amount of weapons in circulation then you're beyond help.
Some people don't have the best intentions, indeed, and providing over the counter weaponry and ammunition surely won't mitigate the amount of shooting incidents or the potential damage they can do.
If anything, it just creates a larger illegal market and increases the risk of people getting shot, bad intentions or not.
Do you really think that an armed populace is an effective way of combatting 'bad guys' and gun crimes??
I think it's already been proven that the right to carry is in no way a deterrent, otherwise we'd have seen less shooting incidents by now, instead the numbers are steadily increasing.
So yes, there are people with ample reasons to own a gun but fending off bad guys really isn't one of them as it's simply not working.
