There is something very dishonest when you rip a comment out of context and try to build up on it. By time Bush said the "not black and white" comment, he had answered the same question about 20 times. And just because you ask the same question another way doesn't make it different. Donald Rumsfield is very good at calling reporters on that trick.
I wonder if Ford believes that all of the IRS "rules" are black and white? Give 20 tax experts a tax return and they'll come up with 20 results.
