The question isn't about whether you can get in trouble for invoking it. The question is about whether or not invoking it indemnifies you from the consequences of the deviation from regulations. I.e., sure you can imagine it and not be punished for violating regulations, but if what you do that violates them is reckless, wrong, unnecessarily dangerous, are you still protected from punishment.
