Really? Have you ever held a clearance? Having held a TS//SCI clearance I can say that how classified information is protected is itself classified (and varies compartment to compartment), so if you did hold a clearance you just violated your NDA with that little comparison, that or the comparison is invalid. Unfortunately the classified nature of the discussion precludes any further analysis of the validity of the comparison as I don't intend to violate my NDA.
The Founders understood that rights are a balance, simple evidence of this is how they could affirm the right to life, liberty, and the pursuit of happiness while implementing capital punishment and imprisonment for certain crimes. It is valid to say a situation does not carry enough gravity to override a right; however, there is no jurisprudence I'm aware of that argues a right is absolute in all situations.
Personally, I think some measures have gone further than can be justified and would not stand up under strict scrutiny (a constitutional law concept). But, even if I am right it does not make the argument you just made valid. Suspending liberties during a crises (right or wrong) has a long history in this country and is even enshrined in law and jurisprudence. That does not make the restrictions right in every case, but it does require more nuanced arguments to defend liberty.
