Bush should have _NEVER_ nationalized them, at least as a private entity they existed in a sorta gray area. Now they are clearly violating the 1st, 2nd, 4th, and 10th amendments.
And the solution isn't another bullshit supreme court amendment of the absolutist language in the bill of rights/etc but to actually have a national discussion about how much safety the are providing vs their cost, intrusiveness, etc and actually find enough common ground to amend the constitution. Until then they are unconstitutional and the court makes a mockery of itself and delgitimizes then entire apparatus in any ruling that doesn't tear it down as such.
And before anyone says "oh thats hard", i'm going to argue no its not, pretty much 100% of the country could agree to amend the 2nd to ban the private ownership of nuclear weapons, there isn't any reason that it shouldn't be possible to get 70% support behind some simple restrictions "aka no guns, detected via a metal detector on public airplanes" passed. But then the agency wouldn't be given free run to do whatever the political appointee of the week feels like. But there are "powers" that are more interested in tracking you, selling worthless scanners, and creating jobs programs for people who enjoy feeling people up and picking through their dirty underwear.
