That's good philosophical thinking. Still, I don't believe for a second the the Military of today would KILL their family members. Most likely we would see a Military coup, or the least a mutiny within the middle ranks of the military. Can you really see Marines marching through the streets and killing American citizens? I don't - this is not Selma, Alabama of the 1970's.
They believe in their Oath, and demonstrators are not domestic enemies. Those guys get it, plus they are really pissed of on how they've pissed on of late. Talk to a Marine or Army grunt. Ask them if they would fire on their citizens who are fed up with the Marxist tendencies of this administration.
I was a simple Aviation Sailor for 11 years on a flight deck, and even us know-nothing non-political Sailors ocassionally discussed if we had to launch aircraft with Marines aboard against our own countrymen. EVERYONE said no. We knew it not only to be "wrongful orders", but just wouldn't do it. The Marines thought the same thing. It won't happen today, either.
“If the federal government gets it’s way, and the supreme court sided with them the Constitution would be completely irrelevant.”
I’m sure now, given that SCOTUS has a “wise Latina women who brings her rich diversity of experience” to the Court, will be able to sway those other legal-knuckle draggers (like Scalia), to see the inherent wisdom of FedGov dominating the States. //not
