Exactly. Ron statements are defensive, overly cautious, non informational, limited, deflecting, etc.
Like Misty he limits comments to common phrases and does not venture anything further, it is as if he does not want to say something that opens himself up to further questioning or trip up. It is like he is being questioned by a foreign enemy and only wants to recount his name, rank and, number.
Ron does not engage in discussion where there are comments like the girl and Larry, he is not proactive, investigative, explorative, even interested.
When asked one time by NG Ron simply stated that it was the job of LE to investigate so he was not asking hard questions or following up on inconsistencies. WTH? I would be personally and passionately involved not dismissive and delegating.
Finally, when talking about Misty, Misty's inconsistencies and, whether Misty has the key --- Ron always makes me feel he knows two versions of the story -- the public version we all know and the private version --- that's why he struggles there and cannot confuse the two with details.
