Mass shootings

[Sociopathicsteelerfan]

My dad related the other day how, at the hardware store when he was a kid, was a barrel of Enfield rifles at the end of one of the aisles. All you had to do was pick one out of the barrel, put it in your cart and pay for it at the register. This begs the question, with such easy access to firearms back then, with zero restriction on purchase, did they not have the mass shooting problem back then? You'd think with the millions of returning WW2 vets with PTSD there'd be a huge pool of candidates for mass shootings, and yet, virtually none.
