At least Mr. Fitzgerald is admitting that the purpose of of his inquisition was not to find the truth, but to manufacture prosecutable crimes.
If it is demonstrated that Fitzgerald already knew that no crime was committed, how could his investigation be legal?
I mean, that's like the police pulling you in before a grand jury to find out who robbed your neighbor's house, when no robbery had actually taken place, and then charging you with lying about the last time you visited your neighbor.
Or like the old example, interrogating you about when you stopped beating your wife.
perjury shmerjury. Lying to investigators is only bad if Clinton does it.
