Ahh interesting, I didn't realize that TouchID would also require a password periodically, I don't have much faith in fingerprint ID, but the required password helps. I like your idea of the duress fingerprint since the police can demand that you supply a fingerprint to unlock a device (but can't demand a passphrase). If you use the wrong one then "Oops, I was so stressed out I forgot which fingerprint to use". I really think it's unlikely that law enforcement will ever take an interest in my phone, yet I still like knowing that my data is my data.
