Fine. Then why did you give this glib answer: "I was regular Army, not National Guard. My job was outside the US borders".
So all of that explanation aside, tell us: did the marines deployed to Los Angeles follow lawful orders? Yes, because it was under a defensible, but patently false, pretext? Yes, even if you knew it was to police not protect and you knew that many of your fellows might well go way beyond that if ordered and that any right or wrong would be decided well after the fact in, if there ever was one, a court of law?
Thanks for the homework and I'm happy you stood up but it is a lot more complicated than the deep details of an oath that most cannot recall or think matters when orders are given.
My position stands: the police and the military will be the instruments of the undoing of our democracy, if it happens, and nothing in your explanation would prevent that truth.
