I'm not really sure why law enforcement would need access to a device. Online activity as well as voice and sms communication can be accessed without accessing a phone. What they may want though is access to iCloud and iMessage networks. I expect that, regardless of how big Apple is, they will eventually be made to store encryption keys in future IOS releases. Will we be more safe from terrorism? No.
If the cops want the contents of the text messages all they have to do is pull the sim card out, assuming the SIM card hasn't been PIN locked, put it in another device and wait.
The contents of email, skype, imessage, icloud, etc is only partially on the device to begin with. If a suspect is suspected of a crime by which the communication is by text message, the above is correct, pull the sim card. If it's by Skype, then that is overly reliant on the phone to stay logged in.
Smartphones are rapidly being able to replace keys and passwords for services not on the phone itself. So a biometric key should always be connected to a "something you know" key. The biometric should only unlock convenience features (eg Applepay, non-progression games, calculator) without the PIN, and require the PIN to be entered before any data-usage or data-storage is unlocked. For example, dropbox should be inaccessible until the PIN is entered. Games that don't save progress (eg card games) should be allow a guest to play without needing to PIN unlock as long as the owner of the device biometricly unlocked it before starting the game.
You get 10 attempts, you have 10 fingers.The other option of course is to use the "wrong finger" 5 times but much harder to do in a pinch. And of course 99% of people probably use their thumb or forefinger. Hmm, i guess we should all set up our off hand ring finger for touch ID, they'd never suspect that one![]()
Admittedly, when you have a case on the iphone, it actually makes the touch id harder to operate, so you may nuke your phone simply from holding it wrong.
