First of all look at history. Tyrants want total control. That means they want ALL guns. Whether they get them in 1, 2, or 3 different moves is irrelevant to them.
From what I understand of the ability of the NSA ET AL, everything we say on the computer, cell phone, and maybe even the land line is being captured. That is why they are building those data storage sites in Utah.
IMO the present administration doesn't give a flip about collateral damage. If the ends justify the means, AND they can get away with it they will do it. With the media in their pocket, they can get away with a LOT. Seriously they literally stole the election. States that didn't require picture ID had voter turn out of 110 to 175%!! The media does nothing. That because they are not the media. They are propagandist.
Any "fundmental change" will require collateral damage. Again look at history. The only thing that changes are the names.
Now to the question. Will a revolution work? Look what happened when a unprepared army goes up against a prepared, and technology advanced army head to head. Can you say Gulf war 1 and 2??? However guerrilla wars are waged and won, even today. The was is to go old school, no or very little tech stuff.
Every one has to make their own decisions on what they will do. A stand up fight is a loosing fight, simply by logistic. Again history, the people under siege always loose unless supplies can continue to get to them.
My wife and I have spent most of our adult life under the oath. We refuse to live in a USA without a standing constitution. We are to old and broke up to run and fight. We figure you have to die of something.
