The CTO would likely be compelled by the courts to reveal their password.
Even if it did I would still fight it in the courts: Warrantless wiretapping, secret Fisa courts. Guantanamo bay prison. Lawyers and congressional leaders being electronically spied on... I do not think its safe for our democracy to continue giving the government tools to spy on citizens.
Isn't the current case in fact exactly what you would hope to see from a government changing in response to gitmo and warrant less wiretapping? If not - what would you expect to see assuming the govt was changing? Honestly curious here, as you seem to want to fight the govt even in the face of "clear and present danger" and even if they had reformed.
