If the feds can *kill* you for any reason or no reason at all, they certainly can throw you into the slammer for whatever you may choose to utter.

From Thoreau's "Civil Disobedience":

"Under a government which imprisons any unjustly, the true place for a just man is also a prison." [...] "If the injustice is part of the necessary friction of the machine of government, let it go, let it go: perchance it will wear smooth, -certainly the machine will wear out. If the injustice has a spring, or a pulley, or a rope, or a crank, exclusively for itself, then perhaps you may consider whether the remedy will not be worse than the evil; but if it is of such a nature that it requires you to be the agent of injustice to another, then, I say, break the law. Let your life be a counter friction to stop the machine. What I have to do is to see, at any rate, that I do not lend myself to the wrong which I condemn."
