What did the defense object to? He questioned if the State was trying to impeach his own witness?
improper impeachment — judge said it might be helping recollection but Berbnie lost in the exchange — he said ground and pound.
He asked the judge whether the prosecution was trying to impeach or help the witness recollect.
In retrospect, I believe it is more impeach in the sense of overly embellish, or take the term from the interviewing police officer.
