Via Lifehacker: ‘The Virginia Circuit Court ruled this week that you dont have to give up your passcode to police if youre detained. Thats great news, but apparently fingerprints are a different story, so if you have Touch ID enabled, you could still be forced to unlock your phone.
Basically, fingerprints don’t fall under the 5th Amendment like a passcode does, so a police officer who cant force you to unlock your iOS device with your passcode could make you do it with your fingerprint. The solution? If you’re detained, reset your iOS device hold the Home and Power button for a few seconds before you have to hand it over. Touch ID doesn’t work on the first boot.’
