In this hypothetical scenario, the NSL would have to go to Apple the corporation, not to any individual. There isn't any individual at Apple that could implement the demand. There probably isn't even a group of ten individuals at Apple that could do it without other employees finding out. And as smart as you think the US Government is, there's no way they could possibly know who those ten people were. So the letter goes to Apple. They have ample time and resources to push back indefinitely. Demanding that Apple implement a Government dragnet across tens of millions of private devices is so far beyond unconstitutional that complying wouldn't even be fleetingly contemplated as an option. In fact, Apple is the sort of company that would move heaven and earth to ensure that this unconstitutional NSL becomes public. If nothing else, their defiance of it would be fantastic PR. Therefore it would be a massively stupid-ass move for the Government to try. They would have zero prospect of a positive outcome and they know it.
