Yes, Mitchell should have asked Ford, “When was the first time you met BK? How many times did you meet ever him?” - things like that, to show she really did NOT know him, made it up.....
At the end Mitchell did a good job blowing away Ford’s claim of being so emotionally ruined. Getting Ford to acknowledge that she had further social contact with the judge the remainder of her sophomore year of school at 5 or six additional parties she attended with Kavanaugh attending the parties. Plus getting her to state there was no negative interaction between her and the judge at these parties after the party where she felt she was raped and almost about to be killed.
