- Ed Green: Look, Mr. Campbell - the warden says that you've been proclaiming your innocence since you set foot in here.
- Bobby Campbell: Doesn't seem to have done me much good, does it?
- Ed Green: Well, who knows? Maybe today's your lucky day.
- Bobby Campbell: I been up here for twelve years for a crime I didn't commit. The guy who was sent here with me already died in this place. If my lucky day includes two detectives accusing me of another murder, I think I'll pass.
- FBI Agent Foster: I found seven false positives out of the twenty that I tested.
- Serena Southerlyn: It's over a third.
- FBI Agent Foster: Statistically, it's impossible that she just kept making that many mistakes. And it gets worse.
- Serena Southerlyn: How?
- FBI Agent Foster: The original forensics team recovered over a dozen partial prints from inside the car where the victim had been shot. Now, fortunately, those prints were kept in a file at another location. At the time, this examiner declared them all unidentifiable. That wasn't true.
- Nora Lewin: What are our chances if we go after Russo for manslaughter?
- Jack McCoy: We'd have to show she knowingly lied, and that her lie led to Martin's death. But for all we know, she was using her judgment.
- Nora Lewin: The system can't be based just on judgment calls. There has to be a set of standards.
- Jack McCoy: Standards might not take into account the complexity of fingerprint analysis. Everything in the system relies on people's judgment, Nora.
- Nora Lewin: But when people cross the line, they need to be held accountable.
- Jack McCoy: We have no proof that Russo knowingly lied.
- Nora Lewin: Every one of her so-called mistakes was made in favor of the prosecution. To me, that means she was neither mistaken, nor is she incompetent.
- FBI Agent Foster: The methodology is based on the premise that no two sets of fingerprints are alike.
- Mr. Rowan: Yes, but no one really knows what the error rates are, do they?
- FBI Agent Foster: No.
- Mr. Rowan: Which means you can't sit here today and tell us that print is not Campbell's?
- FBI Agent Foster: Well, I don't think it is...
- Mr. Rowan: But you cannot absolutely exclude him, can you?
- FBI Agent Foster: No.
