The point is that the legality of the court order compelling Apple does not depend on whether or not the FBI made a mistake in other investigative approaches.  If the order is illegal, then it doesn&#x27;t matter whether the FBI needs the access it provides or not, it&#x27;s still illegal.  On the other hand, if the order is legal, then the FBI needing it due to a mistake doesn&#x27;t suddenly make the order illegal.
