The latest turn of events in the public battle between the FBI and Apple took another turn over the weekend, with the FBI dropping its demand that Apple help it unlock the phone of a alleged drug dealer.

The FBI had previously stated that its demand that Apple grant it access to the phone of the San Bernardino shooter was a one-off request. This assertion was called in to doubt when it requested similar access to a phone related to another criminal proceeding (the criminal 'forgot' his passcode, it would seem). Yet once again, the FBI has backed down, retracting its request.

Is this a permanent retreat? Or is the FBI keeping its powder dry?
