Study Notes

Establishing Guidelines in Forensic Science

Scientific Working Groups (SWG) set best practice standards for forensic science.
Originated with the FBI, involving North American scientists.
Current standards developed by NIST (National Institute of Standards and Technology) and OSAC (Organization of Scientific Area Committees).
OSAC established by the U.S. government under the President's directive.

Firearms & Toolmarks Subcommittee

Focuses on standards for firearm and toolmark evidence examination.
Includes comparisons of microscopic toolmarks on ammunition and firearm function testing.
Addresses bloodstain pattern analysis and forensic document examination.

OSAC Progress

Development of validation and quality system standards.
Creation of terminology lists and collection/storage guidelines.
Established protocols for report writing and expert testimony.

SWGGUN (Scientific Working Group for Firearms & Toolmarks)

Provides guidelines and training for forensic firearms analysis.
Essential for students to understand foundational roles within these organizations.
Recommended study includes textbooks and resources from NIST/OSAC.

Forensic Science Fundamentals

Admissibility in court requires validation of theories through testing.
The Daubert Standards will be covered to assess scientific validity in court contexts.

NAS 2009 Report

The National Academy of Sciences raised concerns regarding the state of forensic sciences.
Emphasizes the importance of analytic methods and monitoring technology.
Offers resources like the Admissibility Resource Kit for firearms and toolmarks.

Firearms Examination Overview

Firearms examination is a complex field requiring detailed knowledge.
Individual characteristics of bullets and cartridge cases are critical for evidence.
Ballistics covers the study of projectiles in motion, linking physics to firearms science.

Types of Firearms

Distinction between shoulder firearms (rifles, shotguns) and handguns (revolvers, pistols, machine guns).
Understanding of mechanisms is essential for firearms analysis.

Revolvers

Operate with ammo fed into a revolving cylinder for firing.
Cylinder loading requires swinging out or releasing the mechanism.

Semi-Automatic Firearms

Ammo is loaded through a spring-operated magazine.
Each trigger pull results in the firing of a single round.

Squib Rounds

Highlighted as an intriguing aspect of firearms discussions, potentially impacting forensic analysis.
