man, adam, this lawyer, the prosecution went after that defense witness. it was brutal. reporter: last thursday and friday we saw the defense star witness on the stand making good points for the defense, but the judge gave the prosecution the week to prepare. they prepared. they came out with both guns blazing and the prosecutor just hammering at the witness over and over again and the judge getting after the witness for not directly answering the question. and at times the prosecution mocked him professionally leading to exchanges like this. question: you knew he was hooked to an i.v. attached to a pole? answer: which has wheels. question: so michael jackson is walking around the room hold hissure win bag connected to the condom catheter? do you assume that? answer: possible scenario, yes.
