I&#x27;m not a lawyer so obviously I&#x27;m not exhaustively well read on the law but in the case that All Writs <i>did</i> allow any action to be demanded to help with an investigation it would still require there to be an investigation in the first place.<p>To preemptively demand a back door is almost akin to guilty until proven innocent, youre assuming that there will be an investigation in the future where a governments ability to hack a device is required.
