I raised three kids, and I kept them all alive and out of jail and made them into productive citizens of this planet. You pick up a thing or two in 60+ combined years of child rearing.
One of the most obvious? When you get stonewalled, the kid has something to hide, something they really don't want to fess up to.
Without wading into the furor up to my ass, I just want to make one observation about the Rove scandal. They are stonewalling, and that tears it for me. My "Mom-dar" tells me this story has legs, and it probably goes further. If it was a lost mitten, we would have the story by now, but this is bigger, it's a new bike traded for crack. Hence the stonewall.
