Gun tech is OLD tech. As firearms tech advances, weapons that do not use a cartridge will be kept from civilian ownership. Eventually, we will have weapons that will be orders of magnitude less effective against the government than what we have now. That is, unless we fight politically.
Really, our only hope is a political solution. How many of us have written, emailed, or called our senators and congress-people demanding that they support gun rights? How many of us support a national organization that fights for the 2nd amendment? How many of us can enter into a conversation with gun control advocates and keep the discourse reasoned, intellectual, and dispassionate? WE are the vanguard of defending the bill of rights, we are in the right, but too often we sit around and complain that our rights are being stripped from us. The most powerful weapons we possess: political influence on our representatives and personal influence on our aquaintances. That is where our strength lies. We will not have to worry about losing our rights if more Americans believe in those rights. If we have to physically defend our homes and weapons from jack booted thugs, we have already lost much of what we should now be protecting.
