This makes me wonder something. I know that while they can't force you to enter your passcode, they can force you to unlock with your fingerprint. I've heard people ask for a feature where you basically have a "duress fingerprint," since fingerprint is already different than password, would using a duress fingerprint be acceptable?

If you're instructed to unlock the phone with your finger, and your "duress fingerprint" unlocks fake data, then you're misrepresenting that fake data as the real data and would presumably be considered to be making a false statement (though this is just speculation on my part). On the other hand, a "duress fingerprint" that locks out TouchID wouldn't be misrepresenting anything. But it wouldn't surprise me if they could still get you in trouble some other way for knowingly locking out the device after it's been confiscated.

  That would be the technical equivalent to the fifth amendment.

    The 5th amendment says you can refuse to incriminate yourself. It does not say you can lie. Refusing to unlock your phone would be equivalent. Unlocking fake data would not.

I believe if you tap the power button 5 times on the iPhone, it disables fingerprint unlock. Perfect for a scenario where you are afraid you might be compelled to fingerprint.

  This is apparently an upcoming feature in iOS12 but doesn't work in iOS11 now What does work is putting the wrong finger on your sensor until it tells you TouchID is disabled and needs your passcode (which is 5 times) or rebooting your device without logging in.
