ml/nj:When you come back into the United States with a United States Passport, you are an American citizen on American soil.
“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.”
You are exactly right!
Having organizations and rules that are extraconstitutional (Beyond what is provided for in the Cnstitution) has got to STOP! We have a War on Terror, BATFE, ICE, CBP, DEA etc All of which act like the Bill of Rights does not apply to them.
You know why the bill of rights doesn't apply to them? Because they have no compunction against using lethal force against you to make you "comply". That's the difference between them and us. They don't have the constitution on their side, but they do have force, and a willingness to use it. It will continue to get worse, until we start actually resisting them.
