Regaining Trust in the IRS

If you want half of the country to believe that the IRS can be fixed, then we need to be confident that we've gotten the whole story.  We need to know that the people responsible have been punished and that current and future employees know that this is a line that must not be crossed again.  We need an open investigation.
Does anyone feel like we've had that?  No? 
Well, this won't help you feel that way either:

Details of that testimony are interesting. Representative Tom Graves (R., Ga.) asked, “Have you asked the individuals who ordered them to use this extra scrutiny to punish, or penalize, or postpone, or deny?” George turns around to confer with his assistant. Just the fact that the inspector general had to confer to know the answer to this crucial question is amazing. George’s assistant says something to him that is not recorded, but one can see the assistant shaking his head back and forth. Then George responds publicly to the question, saying, “During our audit, Congressman, we did pose that question and no one would acknowledge who, if anyone, provided that direction.”

 And:

Second, George was particularly careful to limit his answer to the “audit phase.” Every IG has two procedures to obtain information. One is audit procedure, to which IG George referred. That’s generally limited to accounting analysis, to determine whether there may be reason to open an investigation. Once there is reason — and there clearly was reason here, given the obviously illegal conduct — the IG opens an investigation, in which investigators, not auditors, pose the questions, the department employees are placed under oath, and, as a federal court has approved, informed that “failure to answer completely and truthfully may result in disciplinary action, including dismissal.” The question is why George’s office didn’t do this immediately.

 The probable answer to the question is chilling. 

Who Watches the Watchers?  This is a question that has plagued government planners since at least the Greeks.  What do we do if we can't trust the people who are supposed to be investigating?  What happens if they are kept from doing their jobs? 
Back during the Plame Affair, a much smaller thing than this, W Bush publicly told everyone in his administration that he wanted them to cooperate to the fullest with the investigation.  It would help if Obama would make some sort of similar statement.  He said this was outrageous.  It would be nice if followed up with some action.
