Please clarify your question. I'm not being a smart guy, but I really don't understand what your question is?
Are you looking for the exact written "letter of the Law" interpretation of the Constitution, or are you looking for "what is meant" interpretation of the Constitution??
Or, are you looking for a specific fact of ommission to justify denying the Bill of Rights to the slave population?
If you don't understand what I wrote it is no use in going any further.
