> forced her finger on Touch ID per the warrant
She was not forced, and the warrant does not state that she could be forced. The warrant, almost certainly deliberately, uses far milder language.
What do you think warrants are? You think they get a warrant and they say, "Can you put your finger on the device?" You say, "No," and that's it? If all they wanted to do was ask you, they would just ask you without the warrant.
By definition a warrant is force backed by state violence
The warrant is the force, current jurisprudence largely says warrant do compel people to provide biometric unlocks because it's not speech the same way giving up a password/passcode would be. Blocking or not complying with a signed warrant from a judge is it's own crime and the only safe way to fight them is with a lawyer in court not with the officer holding the paper (and gun/taser/etc with the power of the state behind them).
