These examples are all National Guard troops, which as I said, is a grey area because they are technically under state control. The actual US military examples are all outside the United States dealing with smuggling on open seas or planes smuggling drugs into the country. That's a federal operation not domestic law enforcement.
There's only one of your examples that vaguely references the use of Army troops in Humboldt County in 1990. The title of the article says a lot, "Military Takes Part in Drug Sweep And Reaps Criticism and a Lawsuit." From Wikipedia: Though the operation was scheduled to continue until August 10th all operations ceased on August 5, most likely due to the escalating demonstrations.
So no, you have not made a case that US military troops are involved in domestic law enforcement, and especially not Army Special Forces as you wrote. You described that as a clandestine operation, no wonder.
I think the vast majority of Americans don't want combat troops performing domestic law enforcement. You can like the military without wanting martial law. The current trend in public opinion in state after state is to legalize marijuana, not bring in the military. Grow it legally, tax it, and treat it like alcohol, what a concept. If it doesn't work, we can always go back to what ain't working now.
