A bit of a digression

I have had this much of a quote or saying regarding personal privacy bouncing around my head.
"If/Since you have nothing to hide you won't mind my searching/looking..." Here's where it gets fuzzy for me.
Can someone give me the actual wording and maybe where it's from? Thanks. jason

Your quotation gets fuzzy for me, too. Here's a carefully delineated one to counteract it:

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. [Fourth Amendment to the Constitution of the United States; effective Dec. 15, 1791]
