I was concerned about this for several years and finally articulated this in a vanity in June of 2014 here (when I was Cuban Leaf):

At the time I saw the most risky period as between summer of 2016 and Jan 20 of 2017. The thought was that the plans and preparations were being made for this time period.
I really hope I was wrong, but I AM buying a lot more ammo.
You may be able to hold off your neighbors but when the swat teams show up they will have truckloads.
I used to believe that the military would never fire on their own citizens. May I remind you what happened in the Civil War. Besides remember Obozo proposed a civilian police force with power equal to the military in every way. If you include the National Guard in that force they may come close. Remember Kent State when ordered to fire they did.
