3. CSI Effect Exam Summary

Vocabulary flashcards covering forensic reporting standards, report components, chain of custody rules, and the judicial impacts of the CSI effect.

Forensic Report

A formal scientific document that records the examination, analysis, results, and interpretation of forensic evidence.

NATA (National Association of Testing Authorities, Australia)

The organisation that accredits forensic testing laboratories in Australia and assesses their compliance with relevant standards via regular site visits and reassessments.

ANZPAA (Australia New Zealand Policing Advisory Agency)

Unique Case Identifier

A mandatory component of all written forensic reports that links the report to the correct investigation.

Clear End-of-Report Indicator

A mandatory component of all written forensic reports that establishes where the official report finishes.

Limitations (Forensic Reporting)

Known factors that may affect the reliability or interpretation of forensic testing results, which must be clearly identified rather than concealed.

Opinions (Forensic Reporting)

Professional interpretations that must be placed in a separate section from findings/results and require the author to hold relevant qualifications and experience.

Chain of Custody

The documented record of the possession, handling, and transfer of forensic evidence throughout an investigation.

Signed-Transfer Requirement

The procedural rule stating that whenever evidence changes hands, the person transferring it must sign it out and the person receiving it must sign it in.

Break in Chain of Custody

An incident where evidence cannot be fully accounted for, such as an undocumented transfer, potentially resulting in questions about contamination, integrity, or reduced evidentiary weight.

Investigative Role Separation

The division of responsibilities among detectives, evidence collection teams, and evidence processing teams, which helps prevent contamination, evidence destruction, and bias.

The CSI Effect

The influence of fictional crime television programs on public perceptions, generating unrealistic expectations regarding forensic techniques, investigation speed, and scientific certainty.

Statistical Framing (in Forensic Evidence)

The manner in which forensic probabilities are communicated (such as stating a $1\text{ in }50$ chance versus excluding $98\%$ of the population), which can alter how jurors interpret evidence strength.
