State and federal defenders facing latent-print examiner testimony claiming individualization.

Daubert Challenge, Latent Fingerprint Individualization

FRE 702 motion + cross-exam bank to challenge latent fingerprint testimony. PCAST 2016 §5.2 grounded.

Concede foundational validity (per PCAST), then aim the cross-exam at PCAST's 1-in-18 false-positive rate, the number jurors must hear before they take the examiner's 'match' as certainty.

Summary of cited source
PCAST reported that latent-fingerprint false positives may occur as often as 1 in 18 cases (Miami-Dade 2014 study).
PCAST, Forensic Science in Criminal Courts (2016), latent fingerprint analysis, citing the Miami-Dade Police Department Forensic Services Bureau study(opens in new tab)

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

01.
Not undated boilerplate: the PCAST 2016 latent-print finding is source-linked to the report, so the citation is one you can verify before you file. PCAST classified latent prints as foundationally valid BUT with a substantial false-positive rate, most defense motions miss the second clause.
02.
FBI's 2011 black-box study reported 1-in-306; the more conservative Miami-Dade 2014 study reported 1-in-18.
03.
Examiners are still trained to claim 'individualization to the exclusion of all others', a phrasing PCAST explicitly rejected.

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.

No. Every citation in every brief carries a source URL stored alongside. Lead authorities are PCAST 2016, NAS 2009 / 2014, NRC 1979 / 2003, FBI/DOJ 2015. All are public-domain and linked to their original publication pages.
