Yes to both questions. Statements made in low tones of voice at the bench are to keep the discussion away from the jury, but not from the trial record. The court reporter and/or the court taping system are to record such things, in order to make them part of the trial record.
To add further to this, it is comical to be sitting in a quiet courtroom with nothing but the tone of whispers of the lawyers and the judge at the bench to hear, and to suddenly have the court reporter yell out, “I’m sorry; I couldn’t hear that” in a normal voice. You want to see a room full of people jump?
I should note that in some hearings, I’ve seen the court reporter scoot over to join the discussion, but in some court rooms, the judge and attorneys stand around a microphone directed at the court reporter, who listens from his/her station via headphones. It is in the latter scenario that the situation I described above occurs.
The expert was not a rebuttal witness, because he was offered as part of the prosecution’s case-in-chief. Remember that Vinny later recalls the man during the defense’s case, to bolster Lisa’s testimony and further impeach the man’s prior testimony.
I think you’re misremembering the movie. By this point, he’s already beaten all of the prosecutions witnesses into hamburger, and Vinnie’s long since demonstrated that he’s a lot smarter than he initially appeared. The FBI expert is the last witness called by the prosecution.
One of the really interesting things about this movie is that, like a lot of movies based around a Southern/Northern culture clash, one of its central themes is class conflict. Unlike just about any movie set after the Civil War, though, in this film its the Southerners who are upper class, and the Northerner who represents the working class “everyman.”
True, but he’s done so largely on “street smarts” up to that point. He’s shown he’s a logical, canny arguer, but not that he’s a competent lawyer. By *finally *managing a cogent objection using conventional legal vocabulary, he’s thoroughly surprised the judge–who promptly overrules him.
And you’re right about classism. Very interesting. It really turns the “common-sense country boy upends the city slickers” trope on its head.
