It is a general principle of law that when the government wants to criminalize acts other than traditional common law crimes like murder or theft, it must set out with great specificity the conduct that is forbidden. To visit the rigors of criminal indictment, trial and punishment on someone who has done nothing that is specifically forbidden is unjust -- the very definition of injustice."No crime?"
That leaves the question of whether Rove, Libby or someone else will be indicted for perjury, obstruction of justice or making false statements in the course of the investigation. But why should there be indictments if there was no crime?
Someone please inform Mr. Barone that "perjury" is a crime... that "obstruction of justice" is a crime... and that "making false statements in the course of a criminal investigation" is a crime.
