It's reason enough for me. My problem with TSA is that I'm put in a situation I don't control, where complete strangers have the final say over whether another complete stranger will make uninvited physical contact with me. Strangers do not touch me, ever.
Implied wherever you go is that anyone can be searched on "reasonable suspicion" by law enforcement. If it comes to that, you have no say in the matter. I'm not saying that you have to like it given that you believe strangers can never touch you, but that's been the reality of living in the US and most of the world. I suspect that if it ever came down to a cop frisking you on suspicion that a bulge in your clothing may be a concealed weapon, you'd probably make an exception.
Exception? Not without consulting a lawyer first to see if there's any grounds for a constitutional lawsuit against the cop or their department. Yes, really. Principle matters that much to me.
My rights come first, period. I concern myself with safety only once my rights are guaranteed. We have to push back, hard and constantly, to keep TSA et. al. in check. I think it's time I had words with my elected officials again. Durbin proclaims to be Mr. Illinois-Is-The-Nation's-Rail-Hub, maybe he'll care. They need to know that we're not going to stand for TSA in train stations. That agency has done enough damage already and APD has always been more than capable of handling rail security without harassing passengers.
Either way, I'll report on what I see when I'm at CUS, WAS and PVD in a couple weeks. Holding out hope that the Metro/CA lounges will be TSA-free, or that boarding via a Red Cap will circumvent any TSA BS, but whatever happens I'll let you all know.
You certainly have the right to ask if there is a reasonable suspicion and deny a frisk if the answer is no. Some cops do ask if you'll consent to a search on a hunch without reasonable suspicion.
However, if the answer is "I believe I have reasonable suspicion - please place your hands behind your head" that's your obligation under the law in pretty much every state, and it's not unconstitutional. If you don't voluntarily do as such, you could very well be arrested for obstructing an officer, with more strangers touching you then you'd bargained for in the first place. You'll be able to contact your attorney at that point.
A lot of times this happens, they make the arrest, and then drop the charges. However, it's no fun being arrested. So if the principle is important enough to you to risk getting cuffed and taken to a police station, then be my guest. We live in a constitutional democracy, but our individual rights are not absolute. While the Fourth Amendment protects those in the US against unreasonable search, that doesn't preclude a reasonable search. If there's a search warrant that includes an allowance to search your person, you most definitely won't be allowed to contact your attorney before the search occurs.
