IRS, Koskinen and Body Language

I watched goodly parts of the testimony by the IRS Commissioner John Koskinen before the House Ways and Means Committee.

I'm no body language expert, but even a novice could tell Mr Koskinen was being anything but forthright in his demeanor, statements, and answers to questions.  First of all, when sworn in and told to raise his right hand and swear to tell the truth and nothing but the truth he held his right hand slightly above waist level palm down.  That in itself was insidious and  had all the appearance of announcing he intended to slide by without revealing anything of substantial truth.  His overall demeanor was one of smug arrogance which came off as a bluff to cover the truth.  His answers obfuscated facts like when he said the IRS had not lost a single email since the start of the committee's investigation.  Well, yes, the committee, and the rest of us, are interested to know what happened to Lois Lerner's emails back in 2010 and 2011, not since the committee launched its investigation last month.  His condescending mannerism as he explained the loss of the emails was about as valid and convincing as the school kid that told his teacher the dog ate his homework.

I would dearly love to see a body language expert's analysis to Mr. Koskinen's appearance before the committee.
