All of the establishment is in on it. There are no other motives for their ambivalence.
Issa will not bring himself to ask the really tough questions and let logic pave the way for the obvious follow-ups. Why, one might ask? It is very simple, they just cannot wait to get their hands on the wheel for their little spin around the block.
That's one way to look at it. Another way to look at it is that these people are not all that smart. Evil or stupid?
I watched the Ways and Means hearing on Friday. One example. A Congressman asked about the serial number on Lerner's hard drive. Koskinen answered that he did not know that hard drives HAD serial numbers. Here is a wide open door.
Not only does every HD have a serial number, that number exists somewhere today. How does IRS document who has what hardware? Who has custody of the logs? What is the procedure for destroying government data storage that still has data on it?
They should be asking questions that they ALREADY KNOW the answers to and from then attack the lies and professed ignorance they get back from the witness.
