During an investigation, people who lie and mislead, obstruct justice and perjer themselves while under oath are most certainly committing crimes, regardless of the outcome of the rest of the investigation.
Nobody is saying all GOP is bad, corrupt, or rife with liars (at least not any more than the Dems). But if a guy blocks a criminal investigation as Libby did, those are felonies.
If it's not too late, try not to let your loyalty to all things GOP taint your ability to observe fact.
