May I?
The original intent, as worded, was to ensure that citizens could keep a firearm lawfully, in order to belong to a "well-regulated militia" meant to safeguard "the security".... which could mean basically to repel marauders, attacking Natives, foreign government soldiers hoping to invade, perhaps even an American government-gone-mad. What you (plural you) gun-humpers always ignore is that "well-regulated militia" part. The writers envisioned a local citizen army of sorts, there being no standing national army at the time. Were the French to try to encroach upon the states and grab territory, were the Natives to try to overrun a settlement.... they wanted the citizenry to have the arms and the training (that "well-regulated militia" thing again) to stand against them to ensure "the security of a free State." There is absolutely nothing in there about citizens having legal access to the same firearms used by law enforcement or military. That's all made-up bullshit stuff by the NRA and the gun makers.
It's human nature to admit that you were had, that you're just a puppet. But there you go, Puppets.
