Is this indictment bad?

I am curious to know what my few readers think of this indictment. Both Kristof and Tierney said that its bad that special prosecutors have so much power and thought it would be a tragedy if Bush administration officials would be indicted on borderline charges that weren't the original charge (i.e. violation of the 1982 law making it illegal to knowingly disclose the identity of a covert CIA agent). But if during the course of the investigation people lie about what happened, shouldn't that be punished? If Pat Fitzgerald caught four separate instances of where Libby lied to the grand jury and FBI agents, I'm sure there were more. If administration officials weren't charged on such things, they would have no incentive to cooperate with the investigation -- they could just lie about what happened and not be charged on anything.
