(I don't actually have to insert anything to your example CD, it's invalid, the premise does not have the power to make any assertion that follows lead to the conclusion, necessary and sufficient conditions - the conclusion is false -because- the premise is false.)
I was referring to your example, which in it's original form, is a valid modus poenens. But you cannot assert anything about the truth of the statement as a whole once you assert not-p. It's fallacious, end of. It has -no truth value whatsoever-. It is merely an invalid, unsound argument at that point.
Fucking post editing ninja, that's what you are.
