From TFA: Why not just give up my liquids and/or tell them medical info?
Because it's a violation of my 4th amendment rights, and because the law (including TSA rules) do not require me to do so. (Not to mention, they're not HIPAA compliant)
I tried to be extremely polite throughout, even though I was pretty angry. I don't think that yelling helps anything. But there's a big difference between being polite, and giving in to an unlawful demand.
I don't believe that I should have to give up my privacy *or* my ability to bring with me liquids of my choice. Their job is simply to make sure that what I bring isn't an explosive, and I totally support that. If they want to x-ray, ETD, LCS scan, whatever, I'm perfectly cool with it.
Maybe you should have read the article...
His own question implies that he would have been allowed in with his juice if he provided the medical reason why it is needed. Without a medical reason you don't have a "medical liquid" you have a "liquid".
He can't have it both ways; you can't claim to be exempt from normal procedure based on a disability and then refuse to provide any information about it.
Also "policy" is not the same as "law".
