Factual error: Tommy Molto stands up and tells Judge Lyttle that the prosecution has not been able to find a key piece of evidence: a bar glass found in the victim's apartment. The jury is present when Molto makes this statement. That would never happen in a real courtroom. The judge had not yet decided whether testimony about the glass could be offered by the prosecution, so he certainly would not want the jury to hear anything about the glass until AFTER he made that decision.
Factual error: Judge Lyttle holds several private discussions with the lawyers outside of chambers without having a court reporter present. A court reporter would always be present in such situations. The point of those private discussions is to prevent the jury from overhearing them, but they are still on the record.
