CDs facing microscopic hair comparison expert testimony.

Daubert Challenge — Microscopic Hair Comparison

FRE 702 motion + cross-exam bank to challenge microscopic hair comparison testimony. FBI/DOJ 2015 review grounded.

File a Daubert motion citing the FBI's own 2015 finding that 96% of pre-2000 hair-comparison testimony contained errors. Demand mtDNA testing as the alternative.

“Out of the 268 cases where examiners provided testimony used to inculpate a defendant at trial, erroneous statements were made in 257 of them — or 96 percent of the cases.”

What this template gives you that the discipline-specific treatise does not.
  1. 01.

    26 of 28 FBI examiners provided erroneous testimony or reports across nearly 3,000 reviewed cases.

  2. 02.

    Defendants in 35 of those cases received the death penalty; errors appeared in 33 (94%) of those.

  3. 03.

    Mitochondrial DNA on hair has been routine at the FBI since 2000 — refusal to mtDNA-test is itself a cross-exam line.

Frequently asked questions.

What does the brief contain?

Seven sections: cover (your case identifier + jurisdiction stamped on), reliability standard recap (Daubert v. Merrell Dow factors), the lead authority's verbatim finding with source URL, the cumulative-error history with cited exonerations / IG audits / appellate opinions, recommended FRE 702 motion language (~250 words editable), a 10-15 question cross-examination question bank, and the methods + source URLs bibliography.

Is this legal advice?

No. The template is a research artifact modeled on the published critique literature for this discipline. Counsel of record adapts the motion language to the controlling circuit's FRE 702 doctrine and the facts of the case before filing.

How fast is delivery?

Stripe checkout completes in seconds; the PDF is emailed to the address you provide. Templates are pre-built — there is no per-case data pipeline running.
