Federal Air Marshals are suing to have their gag order removed:

The lawsuit alleges that the Federal Air Marshal Service rules are an attempt to smother and prevent the disclosure of information by federal air marshals of agency mismanagement, fraud, waste and abuse. In addition, the lawsuit challenges the Federal Air Marshal Service actions in investigating the Federal Air Marshal Association in an attempt to identify FAMA members, its Board of Directors and other private information about the organization...

...FAMA legal counsel Stephen G. DeNigris called the agency regulations at issue unconstitutional both on their face and in their application. He asserted the regulations were “nothing more than an attempt by the Federal Air Marshal Service to prevent oversight by Congress and the public at large of an agency rife with mismanagement and pettiness.”

Yup. No doubt in my mind.
