What is subclass carryover in terms of physical evidence?

What did the 2007 NAS report discuss?
The crux of the report is the “badly fragmented” state of the forensic science community. The report points to the disparities in funding, access to technology, training of personnel, and certification among various federal, state, and local law-enforcement agencies.
What organization certifies crime laboratory scientists based on proficiency?
ANSI National Accreditation Board (ANAB)
Ideally, the easiest path forward would be for ANSI National Accreditation Board (ANAB) to require certification of all forensic science practitioners through a body accredited under ISO 17024.
Who was responsible for developing forensic microscopy?
Philip O. Gravelle, a chemist, developed a comparison microscope for use in the identification of fired bullets and cartridge cases with the support and guidance of forensic ballistics pioneer Calvin Goddard. It was a significant advance in the science of firearms identification in forensic science.
What are the 5 types of physical evidence?
The most important kinds of physical evidence are fingerprints, tire marks, footprints, fibers , paint, and building materials .
What are subclass characteristics?
Subclass characteristics are defined. 3. as discernable surface features of an object which. are more restrictive than “Class Characteristics” in that they are produced incidental to manufacture, 2) Are significant in that they relate to a smaller group source and 3) Can arise from a source which changes over time.
Which best describes how forensic scientists used experimentation in the investigation of Pan Am Flight 103?
Which best describes how forensic scientist use experimentation in the investigation of Pan Am flight 103? Conducting explosions in mock up aircraft. Which describes the role of the forensic chemist in the Pan Am flight 103 investigation?
What is the NIST standard for fingerprint identification?
The standard provides methods for agencies that use automatic fingerprint identification systems obtained from different suppliers to exchange fingerprint information.
How are fingerprints used in the AFIS system?
The fingerprint images can then be photographed, marked up for distinguishing features by latent fingerprint examiners, and used to search an automated fingerprint identification system (AFIS). [1]
Is the accuracy of forensic fingerprint evidence reliable?
The interpretation of forensic fingerprint evidence relies on the expertise of latent print examiners. The accuracy of decisions made by latent print examiners has not been ascertained in a large-scale study, despite over one hundred years of the forensic use of fingerprints.
What was the outcome of the NAS report?
Based on its findings, the NAS report made thirteen recommendations, including the creation of an independent, scientific oversight entity for forensic science, investing in research and standards setting, addressing cognitive bias in the practice of forensic testing and educating judges and legal practitioners.
