No-one can disprove it.

Through some surfing, I find this post from back in September, describing the best defense of George "Macaca" Allen ever. You may recall that at some point some college buddies of Allen's came forward to testify that they had heard the Senator using other racial epithets in one of those mistakes of youth. And one blogger explained why this probably wasn't a big deal:

Pardon me for pointing it out. But thirty years later remembering a brief distant conversation outdoors by a pond, isn't it quite possible Taylor heard the word ["]neighbors["], as opposed to the other? I doubt he'd hold up on the stand in a court of law.

Of course! If only Mark Fuhrman had used the same defense, his testimony might have put O.J. Simpson behind bars!
