I don't have a problem with SA whitelisting the TSA or any other government agency.
The only thing that I would need before whitelisting is for each agency to post a video on their website of all senior management removing their shoes, their clothes, pass through a metal detector, submit to a body cavity search and sign a statement that they are indeed not spammers. With these prerequisites, I think we could come to some kind of agreement to whitelist them, otherwise I am happy the way it is. :-)
