◀ Recross-examination of Gary Sims Remaining witnesses and lunch break ▶

Witness: Gary Sims
Examiner: Tom Lambert
Called by: Plaintiff • Date: Friday, November 15, 1996 • Utterances: 10

Lambert conducts a brief redirect to rehabilitate Sims on the product rule used to calculate DNA statistics. Sims confirms that both the 1992 and 1996 NRC reports endorsed the product rule, and that subgroup variation would not meaningfully change his statistical conclusions.

# 1 MR. LAMBERT:

Just a couple questions on this final point, Mr. Sims.

FURTHER REDIRECT EXAMINATION BY MR. LAMBERT:

# 2 Q:

The 1996 most recent NRC report, it endorsed the product rule that you applied here, didn't it, sir?

# 3 A:

Yes.

# 4 Q:

Even the 1992 report, that did endorse the product rule?

# 5 A:

Yes.

# 6 Q:

These little nuances between subgroups, would that change dramatically the 1 in 57 billion to the 1 in 150 billion number that you have up there?

KEY QUOTE

# 7 A:

No.

# 8 MR. LAMBERT:

No further questions.

# 9 THE COURT:

Thank you.
