re: #84 Dr. Matt
I’ll venture to guess that the families of the 26 dead wish the shooter was using an actual “varmint round”.
On the contrary, I posit that this sort of event would be a lot less likely if the only rifles available were firing larger and heavier cartridges that result in longer and heavier weapons that are massively ill-suited to urban combat and firing at high rates of fire in close quarters.
This is, after all, why a rifle from WW1 or WW2 is quite appropriate to modern hunting but not to modern warfare. The latter changed (not a lot of aimed half-mile shots from trench to trench), and the tools changed to follow.
Perversely, I think if anything we need to be more heavily regulating the smaller cartridges.
