&gt; Under penalty of perjury, not really.<p>Since you&#x27;re quite obviously having to dance around how to communicate the fact that you&#x27;ve received NSLs and invocations of CALEA that made you feel queasy (I feel your pain for similar, vague, hypothetical reasons), perjury isn&#x27;t the legal concept that you&#x27;re after there. You want 18 USC 2709, and for those keeping score at home, to my knowledge nobody has been prosecuted for violating (C)(1) which would test that law on appeal. The Internet Archive famously challenged the nondisclosure itself and won, which is a bit different.<p>I honestly don&#x27;t know with what they&#x27;d charge you. Obstruction, maybe, but there&#x27;s enough national security buzzwords in the (again, I&#x27;ve heard) letters and law to give me pause on considering civil disobedience there. The law does say in 18 USC 3511 that they can invoke a district court to force compliance, and then contempt can follow. But unclear on the nondisclosure part in the absence of a court order, and that&#x27;s scary.<p>(BTW, IANAL, just an ex-hoster with a penchant for policy, and I&#x27;d love to hear someone like rayiner&#x27;s view on this.)
