You used the word "feel" four times in your post, but it appears zero times in the fourth amendment:

> "The right of the people [1] to be secure in their persons, houses, papers, and effects, [2] 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."

The clause labeled [2] limits the scope of the clause labeled [1]. It's not a free-floating right to "feel secure" against anything--people following you, etc. It's a right "to be secure in [your] person" "against" a specific intrusion: "unreasonable searches and seizures."

If it said: "you have a right not to be mauled by lions," that wouldn't mean you have a right not to be eaten by hippos. Much less that you have a right not to "feel" threatened by the prospect of being eaten by hippos.
