Interesting legal take. Similar to "You have the right to search my house with a warrant... you don't have a warrant to make me tell you where the drugs are hidden." But it doesn't actually work that way.
Unfortunately, the courts have ruled that like a search warrant, if you have a key to the front door, you must hand that key over, and that such a key to the front door is not self-incrimination.
I certainly get the arguments here about privacy and security, but for all the chest beating, that's NOT how the law actually works. In the case where the subject of a warrant is alive, you can and will sit in jail until you rot until you unlock that laptop.
The problem here is that while courts come down on some basic rights WITHOUT a warrant, courts have consistently said that WITH a warrant, the police (but really the court by extension) can do whatever the hell they please. So long as there is a warrant.
And the reason courts will say this, and continue to beat anyone over the head who disagrees is that courts actually have relatively little power. Besides contempt charges, the warrant is an extension of the court's power to not only control police, but to control and enforce the law on citizens.
The moment you think you're going to tell any court that they can't do what they want with a warrant, thereby asking them to reduce their own power even further, you've lost your ever loving mind.
This is why things like the All Writs Act matter so much to courts. As the arguably weakest branch, they are going to defend the use of their tools most of all.
And all the brash /. comments in the world won't get you out of prison short of a presidential pardon. Just ask Joe Arpaio about that. And the public jumped all over that because even the public generally sides with NOT removing power from courts.
And forget arguments against FISA. For all the correct arguments about a rubber stamp, the fact that they even bothered to include a court makes the courts themselves tickled pink.
Legislatures can cut funding. Executive branches have guns, bullets, and bombs. Courts only have "Please do what we say... pretty please?"
