You mean the badgering by the two lawyers for the plaintiffs, correct?
No questions asked for the purpose of eliciting facts in these few excerpts we are looking at. Just a little softening up before they get down to business.
See comments #5 and #3 - they put it better than I can!
The entire deposition is over 200 pages. If the lawyers know that a witness has been dishonest/equivocated before, I think it's fair that they have some leeway for these kind of questions.
