When Marcia Clark, O. J. Simpson's prosecutor, tried to counter allegations that Mark Fuhrman planted evidence, she tried that empty argument on the jury and it failed miserably. It will always fail because it implies that it's all you've got. It's equivalent to saying "Uhh... let's not talk about that now" with an embarrassed expression on your face.
