@TryNot2Get2Technical:  If your assertion was true, James O'Keefe would still be an unknown.  But the opposite is true: he found an eager audience for his deceptively edited videos, and he got rich and famous.  The relatively small amount he was forced to pay when sued by his victims pales next to what he makes selling lies.  The trick to this business is a fan base that fervently believes that the content represents truth; any deception involved in the actual filming is irrelevant.

Credibility is not a requirement here; profit is all that matters.
