I really like AG Barr, and his calm demeanor. He’s a bit like the high school principal you’d get sent to for some misbehavior and by the time he’s done talking to you, you realize you were in the wrong. He just takes the emotion out of it and makes good logical sense.
I’ve heard him give a couple/few speeches and he has a wicked sense of humor, and as you said, explains legal matters in a clear manner that anyone other than someone who refuses to understand, will understand.
