iOS 11 ‘cop button’ also helps users w/ Medical ID protect their data if unconscious

iOS 11 beta 6 (released earlier this week) includes a new feature to quickly disable Touch ID from the lock screen. Tapping the lock button five times to access the SOS screen or opening a Medical ID will cause the iPhone or iPad to temporarily reject all Touch ID attempts, requiring a passcode to unlock.
We have confirmed with sources that this behavior is intentional rather than a bug, as well as some explanation as to why it was added. Whilst in theory it can be used to prevent law enforcemen
