This might be great for the FBI right up until they actually try to use the evidence in court.  The defense attorney can claim (rightly so) that unless they can examine the unlock method to verify it doesn&#x27;t tamper with any of the data on the phone, the evidence is inadmissible.<p>The only way the FBI will be able to use this data in court is if they turn the process over to the defense so they can have the process independently verified.  Since the article states that they don&#x27;t have access to the &quot;technical details&quot; of the hack, they have no way to prove the method doesn&#x27;t manipulate the data on the device.
