Suspect Required To Unlock iPhone Using Touch ID in Second Federal Case (9to5mac.com)

An anonymous reader shares a report on 9to5Mac: A second federal judge has ruled that a suspect can be compelled to unlock their iPhone using their fingerprint in order to give investigators access to data which can be used as evidence against them. The first time this ever happened in a federal case was back in May, following a District Court ruling in 2014. The legal position of forcing suspects to use their fingerprints to unlock devices won't be known with certainty until a case reaches the U.S. Supreme Court, but lower court rulings so far appear to establish a precedent which is at odds with that concerning passcodes. Most constitutional experts appear to believe that the Fifth Amendment prevents a suspect from being compelled to reveal a password or passcode, as this would amount to forced self-incrimination -- though even this isn't certain. Fingerprints, in contrast, have traditionally been viewed as 'real or physical evidence,' meaning that police are entitled to take them without permission.Ars Technica has more details.

      There's (not a lot of...) case law that suggests a truly deadman switch that erases a device isn't considered destroying evidence. If you *do* something actively that triggers it, that's destruction and you can be charged. If by doing nothing, the device is erased, that's okay. You're also not under any obligation to mention such a thing exists.

      So for example if you set something up to wipe the device if you sent a magic text message, that would be a problem. Something that wipes if you don't touch it for a week is generally considered legal. It generally goes with the idea that you can be held to consequences for your *actions*, but there's a higher bar to hold you accountable for your *inactions*.

      If [he was compelled to put his finger on the phone], then that's incontrovertibly a violation of the Fifth Amendment.

      As someone who used to stand by that view, nowadays it strikes me as the stance of someone who values their privacy (as we all should!), but who hasn't thought through the ramifications of their stance yet.

      For instance, I'd wager you have no problem when the police swab a suspect for their DNA, nor when a passed-out drunkard is compelled to provide a blood sample in the hospital after a DUI, yet in both cases the suspect is being compelled, potentially against their will, to provide something incriminating of themselves to a machine in the police's custody that will tell the police whether the evidence from the suspect is incriminating or not. That's no different than compelling a suspect to provide their fingerprint to a phone in the police's custody that may have the ability to incriminate the suspect.

      In fact, both DNA evidence and the BAC measurement situation I described have made it through and been affirmed by the Supreme Court already (in some cases, multiple times), for the simple reason that the right against self-incrimination only extends to "testimonial" evidence (a.k.a. "communicative" evidence), not to "real" evidence...nor should it.

      I recall reading portions of the majority opinions for some of the seminal cases in this area a year or two back when researching the topic, and one of them basically stated that if we took the notion that we can't collect incriminating "real" evidence to its logical conclusion, we wouldn't even be able to compel someone to reveal enough of their physical appearance for them to be recognizable to an eyewitness, which they asserted was utterly absurd and was clearly beyond the bounds of the protections afforded by the 5th Amendment. More or less, so long as the police have a warrant and aren't trying to compel any form of demonstration of knowledge (i.e. testimony), they're within their rights.

      You've already said that you're fine with the police collecting fingerprints, which is good, since fingerprints are not testimonial/communicative in nature. But how the police collect and use them is left up to them to decide. Whether they collect them on a piece of paper, via an electronic scanner that stores them to local database, or by way of a sensor that writes them into a transient piece of memory on a mobile device makes no difference. In all three, they're simply compelling the suspect to provide a piece of evidence in their custody to a device or system in the police's custody. It's a simple transfer of physical evidence from the suspect to the police. The means may be different, but the thing being compelled is the same in all three cases.

      That the evidence can be used to incriminate the suspect does not mean their rights have been violated. And the best course of action if you don't like that fact is to stop using real evidence (e.g. keys, fingerprints, etc.) as a locking mechanism.

      Why is my phone not protected because I used a fingerprint while your phone is because you used a passcode?

      The phone is not legally protected in either case. If they can find a way in, they can use the data. What is protected in the latter case is the fact that you know the passcode. If there is anything incriminating on the device then knowing the passcode which unlocks it would be tantamount to an admission of guilt. (Note that the passcode is generally not protected if they can separately prove that you have the ability to unlock the device, since at that point you would not be revealing anything incriminating.)

      The principle behind the prohibition on self-incrimination is that no one who has not already proven guilty should be placed in a catch-22 where their only options are to confess their guilt or be punished for failing to do so. Allowing records to be taken of your physical characteristics does not even amount to providing testimony, much less testifying against yourself.

The right to non self-incrimination does not mean you are immune from having evidence produced that incriminates you!

    The key thing is that it is a right to not testify, or be a witness, which is the act of saying or stating something. If a person can be compelled to produce his/her fingerprints (something which in itself is not a testimonial act), then just because that unlocks something that incriminates the person does not mean they have been self-incriminated.
