That would be my concern too tubercle.
"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."
I think the fourth amendment was meant to protect people in criminal investigations but Im not sure.
If there is a fire in your house when you are not home, and the police and firemen crash in to put it out are they violating the fourth amendment?
When you go to an airport and get on a plane you are knowingly exposing your person to the public. You are also entering a privately owned space where the individuals who own it are able to set the rules.
Another example: Does the first amendment apply in this or any forum?No, the owners or administrators are able to set the rules regardless of the Bill of Rights. We cant just post anything we want here.
When you enter an airport you are entering private property owned by someone else, right? They can set the rules as to what you may have on your person. Since people can not be just trusted to obey the rules that searches should be given.
"What a person knowingly exposes to the public, even in his own home or office, is not a subject of Fourth Amendment protection. But what he seeks to preserve as private, even in an area accessible to the public, may be constitutionally protected. That is, the “capacity to claim the protection of the Amendment depends not upon a property right in the invaded place but upon whether the area was one in which there was reasonable expectation of freedom from governmental intrusion."
= if you dont want to be searched dont go to an airport.
