Although the concept of the exclusionary rule was first addressed in 1920,(Silverthorne Lumber v. the United States) it didn’t get fleshed out until:
Mapp v. Ohio, 367 U.S. 643 (1961)
Wong Sun v. United States, 371 U.S. 471 (1963)
Nix v. Williams, 467 U.S. 431 (1984)
Not exactly a founding fathers concept. There are other remedies and several warehouses filled with cases involving rulings. We are still protected as long as we may be heard.

I grant that it took some time to create and utilize the penalty, but I stand ground: A right with no penalty for the violator, is no right at all.

Look to the Soviet Union for confirmation of that. They did have a constitution, adopted in 1922, revised in 1936 and again in 1977. They even had a Freedom of Speech clause in it, completely ignored in practice, of course. They even went so far as tp accept the Helsinki Accords in 1975, which were a form of a Bill of Rights (among other things). Of course, ignored.
