It is very logical, as revealing a password is considered testimonial and is protected by the fifth amendment.

Right, and pressing your finger on a fingerprint sensor is also revealing a password, just via different means.

Right. Like I said, that's not logical, that's just legalese to gain access where you didn't have it before.

My fiancé is an attorney and I'm an engineer, and she looked at me incredulously when point out anything that is not logical in her legal work. I'm thankful my father talked me out of becoming a lawyer.
