On Friday, 1 August 2014, President Obama held a press conference. Among other issues he acknowledged that in the aftermath of 9/11, "... we tortured some folks ...".
Throughout the vast majority of this segment of this press conference, Barack Obama was leaning on the lectern with his right elbow. This is rare for a President - and President Obama in particular. It sends signals of a beta emotional tone, low confidence, low commitment, a lackadaisical mindset and low priority. Because of this posture, President Obama was only able to use his right hand minimally and it remained largely obscured to the audience and viewing public. The less we see of a person's hands - the less we trust them (e.g., held beneath a table during depositions, voir dire, interrogations, negotiations, during witness testimonies in court, etc.).
This is extremely poor nonverbal behavior for anyone to exhibit - especially a head-of-state - and particularly on such an important topic. It is indeed rare for Mr. Obama. He did display similar body language (see below) against Mitt Romney in the 2012 campaign during the first debate - and that was the one in which most agree Romney beat him hands down.
