"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."
It doesn't say that a right to be secure... is hereby granted. It says since we have these rights to personal security and they are given to us by God, they shall not be violated-- it's an affirmation, not a declaration of something new.
I will agee with you that it is assumed, but I would be a lot happier if it was spelled out so no one could mess with it.
