"At some point, we will become a gun-safe, and then a gun-sane, and finally a gun-free society."
Jefferson wrote: "What country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance?"
The problem we run into is if you take all the guns away from the citizens what would stop a government from, in the future, slowly stripping away other rights until the day comes in which it is no longer a Democratic institution but a benevolent Oligarchy? It no longer fears the people could rise up and revolt, because they no longer have guns. "We can protest" people will say, and they will roll tanks into the squares to crush the opposition.
Tell that to the Chinese and the Tienanmen Square revolt for Democracy that didn't go so well. Tell that to the Syrians who are being slaughtered by a government that out guns them. We were a country born of revolt from a King that sought to oppress us.
The 2nd amendment is read like this:
"A well regulated militia being necessary to the security of a free state, the right of the people to keep and bear arms shall not be infringed."
It means nothing about militia owning guns. It uses the militia as context here. Its recognizing that a militia is important FOR a free state, and the key is the COMMA - the pause to say "Hey we know militias are important BUT..."
The right of the people to keep and bear arms shall NOT be infringed.
That's it. We can squabble about what exactly the arms the forefathers envisioned, but at the time people could own the same guns that were given to military troops. Re-read what I wrote about Jefferson and keeping the government in check.
You give the government all the power - be careful what you wish for.
