Oh, it certainly existed. Conspicuously no stricture on unwarranted spying for purposes of investigation was stated and that had to be read into it later by the courts (which I consider juristic legislation.) It's not clear to me that the framers didn't intend to reserve that right for investigation. I'm not saying it is wrong to restrict it, just that the constitution should have been so amended for it to be considered a constitutional question.
