Terrorist has plans and contacts on laptop/phone. Society has a very reasonable interest in that information.
But of course there is the rational counter argument of “the government designates who is a terrorist”, and the Trump admin has gleefully flouted norms around that designation endangering rule of law.
So all of us are adults here and we understand this is complicated. People have a vested interest in privacy protections. Society and government often have reasonable interest in going after bad guys.
Mediating this clear tension is what makes this so hard and silly lines of questioning like this try to pretend it’s simple.
