Re: "The last time folks tried that, both sides had muskets and cannon.
This time one side has small arms and the other has Apaches."
I advocate nothing but allow me to point out the Military has Apaches not the courts and not the Congress and for that matter not even the White House. Aside from Generals, and Admirals, who are well connected and have every reason to side with the powers that be they may have even more reason to side with the middle class in the country (the reasons I say this should be obvious) As for all other officers and and the Enlisted they are almost to a man or woman a part of the poor or middle class.
They may be very hesitant to fire on fellow Americans, depending on the issue that has the unwashed out in force with torches and pitchforks.
