You say your friend wants proof that McCain didn’t pressure the media ... you can’t prove a negative. Your friend is making the accusation, so the burden is on her to give the proof.

Huh?

Sure you can. Maybe in this case it would be difficult, but "you can't prove a negative" is not a true generalization.

Suppose someone said, "Prove that Barack Obama has NOT stayed in Illinois his entire life." Could you prove it? Of course...just show a single example where he is outside Illinois.
