It's interesting in the case of social media companies. Technically the data held is the companies data (Google, Meta, etc.) however courts have ruled that a person still has an expectation of privacy and therefore police need a warrant.
There's no known technique to force you to input a password.
I fully agree, forced biometrics is bullshit.
I say the same about forced blood removal for BAC testing. They can get a warrant for your blood, that's crazy to me.
Imagine it's 1926 and none of this tech is an issue yet. The police can fingerprint and photograph you at intake, they can't compel speech or violate the 5th.
That's exactly what's being applied here. It's not that the police can do more or less than they could in 1926, it's that your biometrics can do more than they did in 1926. They're just fingerprinting you / photographing you .. using your phone.
