Digby: It's The Cover-Up

There is a reason why the saying "it's not the crime, it's the cover-up" has become a truism in these high profile political scandals. In the first place, no matter who does it, when someone covers up a crime they tend to make it more difficult to prosecute it, obviously. For instance, suppose that Novak and Rove conspired to get their stories straight. You can't prove what was originally said because they've decided to lie about it. But if you can prove that they lied to the authorities or took affirmative measures to obstruct an investigation in which it could have been found that they committed a crime, you prosecute. Committing a crime to cover up something that may or may not be a crime is still a crime.
