What you posit with interrogated Face ID is a method of hacking encryption. You've provided a backdoor, that is the person's face. Previously the suspect's phone was encrypted, now the encryption is broken against the suspect's intent. A warrant was used to break the encryption.

Do you see what I'm getting at? You came up with warrant-breakable encryption, but didn't call it that. This is why it's not an easy question-- the solutions are nuanced, and some are a lot uglier than others.

Maybe? There's a huge distinction between warrant-breakable encryption as a default (because it's easier) and enforcing that nobody can encrypt data unless it's encrypted using biometric data (or other information that is available outside the head of a user)

Furthermore, there was a falsehood of security to begin with. You shouldn't legally be able to say the data is safe when it isn't safe to anyone with a couple photographs.
