I recall the US govt using a question sheet to the military and one of the questions was Would you fire upon US citizens if it were required or something like that. The way I see it, if the govt is probing like that back in the 90's then they had a plan all along. The issue lying in the shadows, at least one of them, is if under martial law, would you fire upon US troops even though they have orders to enforce curfews, food rations, gun collections, public monitoring, and last but not least, rights stripping that violates the constitution? Would you fire upon them to get what you and your family need if they are in your way? Knowing that they have parents and loved ones you might be in contact with or worse, even one of your own? This could be, in a worst case scenario, turn into an Iraq on US soil. Just something to think about .
