In fact, it PROVES just the opposite. It simply proves that the media person saying it is a liar. There is more than ample proof that cheating happened. Anyone with the slightest interest in truth has seen it. For the media to say it doesn't even exist is categoric proof of lying.
I forever distrust every news source that makes this statement. Once a liar, always a liar.
Actually the report of absence of anything can never prove either the hypothesis nor the null. This is the problem with freepers. We emotionally throw around absurd statements lie if the media reports something it proves the opposite. This is why we are labeled conspiracy nuts as much as the DU
We need to do better with understanding debate and principles of proof and theory. We need to provide unemotional evidence to allow others to be lead to the truth.
We have minimal understanding for logic and rhetoric anymore and I fear it is lost generationally if not permanently.
