Reducing Erroneous Exclusions Workshop
The exclusion decision is a fairly recent change in latent print comparisons, and the discipline is still struggling with how to handle exclusions. Erroneous exclusions are being discovered with surprising frequency in latent print units around the country. Many labs have begun to verify their exclusion decisions, and this has resulted in errors finally being noticed. Recent research into the decisions of latent print examiners shows that erroneous exclusions are common and inevitable.
So, what training have you had in exclusions? What is enough for an exclusion? What is your lab's standard for exclusion? Is your lab implementing any new Quality Assurance policies to address this problem?
This workshop will review the policy changes that Arizona DPS has implemented in their latent print unit to reduce erroneous exclusions. Examples of erroneous exclusions from casework will be presented along with information on circumstances that might make an erroneous exclusion more likely. Hands-on comparison exercises will demonstrate a practical approach to exclusion decisions.
This class is intended for latent print examiners who routinely conduct comparisons.
