Brief summary: The FBI and the DoJ want Apple to help them access the contents of the iPhone that was in the possession of one of the terrorists who perpetrated the San Bernardino attack. Specifically (afaict) what they want is for Apple to install a digitally signed update on the phone that will let the FBI brute-force the pin-code without the phone clearing all the data. The FBI assures us that this solution would only let them access the contents of that specific phone and could not be used to access any other locked and encrypted iPhone. Apple seems to believe otherwise. Apple has stated that they could perhaps have helped the FBI by forcing the phone to sync to iCloud and then turned over that data (as they did with older data from that account), following a court order. However, it turns out that the day after the phone was confiscated, the phone's owner--the employer of one of the terrorists--somehow managed to change the ID associated with that iCloud account, making that solution impossible. According to the employer, they did this "in cooperation" with the FBI, which may imply that the FBI is responsible for this situation either due to a fuckup or possibly due to a deliberate decision to compel Apple to provide them with a backdoor that may be adapted to a general-purpose solution.

Anyway, who's right and about what? What should be done?
