@H2O MAN,
If the Second Amendment is really to enable ordinary Americans to overthrow an unjust government, we must take cognisance of the changes which have taken place since the 1770s, when people, as my learned friend pointed out, were still wiping their arses on dock leaves.
To enable this aim to be credible, since the days of muzzle-loading flintlocks and cavalry sabres, we have to to consider helicopter gunships, remote-control drones, strike aircraft and aircraft carriers, goodness a whole Air Force, saying nothing of theatre atomic weapons and germ warfare agents. For reasons of brevity I'll leave much off that list.
So come on guys, get serious, you are a tad underpowered as yet.
Or maybe the law, and the Amendment, is a bit out-of-date and fairly risible in some of its interpretations?
