I've never denied that CA is a combative individual who thinks she can make up her own rules as she goes along, and I agree that this depo would probably have gone much more smoothly in a courtroom, with the imminent threat of contempt of court hanging over CA's head. I still think however, that IMO, JM reacted unprofessionally to her shenanigans and responded in a retaliatory manner.
That's the beauty of Websleuths - all can agree to disagree.
Having said that, it appears that all the lawyers posting on this thread agree that Mr. Morgan acted professionally.
