We? Were YOU on Lincoln’s staff when he suspended the writ of habeas corpus and imprisoned thousands of people for speaking out against the war. If so, you ought to be tried, found guilty, and hanged.

Should those that fire on American troops be tried for treason and hanged?

Should those that fire on American troops be tried for treason and hanged?

That's a good question — the Constitution defines treason as such: Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort.

Therefore, we should ask: is the firing on of American troops necessarily the waging of war on the several states?
No, obviously not — there are [American] troops who are not even citizens of the States.

In fact, you could raise an army and attack DC, burning it to the ground and definitionally it would not be treason.
