The fourth amendment actually states:
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.(emphasis added)
The fourth amendment does not prevent all searches, only unreasonable ones. There is also no per se requirement for a warrant in order for a search to be reasonable. There are a great number of circumstances in which warrantless searches are reasonable and constitutional.
Before that person with money starts their suit he or she may want to do a modicum of legal research. If he or she does then he or she will quickly discover that airport screenings have been upheld as not being a violation of that principle. See: United States v. Aukai, 497 F.3d 955 (9th Cir. 2007) (en banc); U.S. v. Davis 482 F.2d 893, 908 (9th Cir. 1973); see also United States v. Hartwell, 436 F.3d 174, 178 (3d Cir.), cert. denied, 127 S. Ct. 111 (2006).
Airport screening searches are okay if they meet the following standard. It "is no more extensive nor intensive than necessary, in the light of current technology, to detect the presence of weapons or explosives [] [and] that it is confined in good faith to that purpose." Davis, 482 F.2d at 913.
Given the need to secure certain areas, prisons, courts, airports, etc a search to enter is not unreasonable.
This is why we need to be vigilant about keeping the 2nd Amendment; so that it doesn't just disappear like the 4th
In a great number of ways the 4th has actually been bolstered since the time of the founding.
So we have the right to freely travel and move about, with a TON of strings attached.
Could you please cite to the part of the US constitution that gives you a right to freely travel? Lets assume that you have constitutional right right to travel. After all the SCOTUS has recognized it at least in terms of freedom to move between states. And federal law, 49 U.S.C. § 40103, provides "A citizen of the United States has a public right of transit through the navigable airspace." International travel is subject to many more restrictions. That said, what are the "TON" of strings attached? That if you chose to travel by a plane you are not allowed to bring a dangerous weapon or explosive on board and that you must go through minimal intrusive security checks to assure you don't.
