I received my first BB gun at age 5 and a shotgun on my 12th birthday. I shot competively in 4H growing up. Most of the kids in my rural community grew up in a similar household. We were taught respect and discipline through shooting at an early age.
I don't want to get into the politics of the issue today, but suffice it to say, I believe blaming the tools of the crazy instead of the root causes of the crazy is wrong.
