Hey FOX. Define "proof." They're playing games here. Of course, If someone DOESN'T WANT to believe something, NOTHING will be regarded as proof.
Note that in a court of law, "proof" is not regarded as absolute truth of a fact, but rather accumulates to a conclusion "beyond a reasonable doubt" or "on the balance of probabilities." So one can still conjure a "doubt" after seeing damning proof, but one might still cling to "doubt", if you so choose, if it is is unreasonably. FOX is being sneaky (no surprise) because FOX is comped.
