I have been trying for some time to find a good way to teach my sons that lying is not the right thing to do. At long last, I have found the perfect example: Prosecutorgate. I never thought I'd find myself saying this, but here goes: Thank you, Alberto Gonzales and your team at the Justice Department for providing the very high-profile cautionary tale I was looking for. As Messrs. Sampson, McNulty, Moschella -- and, who knows, Rove and Gonzales himself -- are forced to fess up in public, I can turn the TV from Hannah Montana to C-SPAN and tell my kids, "For heaven's sake, whatever you do, don't act like that!" Now I just have to figure out the pre-school equivalent of, "It's always a bad idea to tell Congress things that are directly contradicted by 143 pages of internal emails and documents."
