Scientific Working Group – Bloodstain Pattern Analysis
The Scientific Working Group on Bloodstain Pattern Analysis (SWGSTAIN) was created in March 2002 at a meeting held by the FBI Laboratory at the FBI Academy in Quantico, Virginia. It was decided that there was enough interest in bloodstain pattern analysis (BPA) to warrant the creation of the Scientific Working Group (SWG). According to the guidelines for organizing a SWG, the Scientific Working Group on Bloodstain Pattern Analysis (SWGSTAIN) generated and ratified a set of bylaws in accordance to the Scientific Working Groups published in ''Forensic Science Communications'' (July 2002). SWGSTAIN has nationally and internationally recognized bloodstain pattern analysts, several of whom are members of the International association of bloodstain pattern analysts, International Association of Bloodstain Pattern Analysts (IABPA). The experts come from various areas including law enforcement, federal, state and local laboratories, the private sector, and academia. They also come from va ...

FBI Laboratory
The FBI Laboratory (also called the Laboratory Division) is a division within the United States Federal Bureau of Investigation that provides forensic analysis support services to the FBI, as well as to state and local Law enforcement agency, law enforcement agencies free of charge. The lab is located at Marine Corps Base Quantico in Quantico, Virginia. Opened November 24, 1932, the lab was first known as the Technical Laboratory. It became a separate division when the original Bureau of Investigation (BOI) was renamed the FBI. The Lab staffs approximately 500 scientific experts and special agents. The lab generally enjoys the reputation as the premier crime lab in the United States. However, during the 1990s, its reputation and integrity came under withering criticism, primarily due to the revelations of Special Agent Dr. Frederic Whitehurst, the most prominent whistleblower in the history of the Bureau. Whitehurst was a harsh critic of conduct at the Lab. He believed that a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FBI Academy
The FBI Academy is the Federal Bureau of Investigation's law enforcement training and research center near the town of Quantico in Prince William County, Virginia. The academy occupies 547 acres (221 ha) on the US Marine Corps Base Quantico. It is located 36 miles outside Washington, D.C., and is a full service national training facility.

Bloodstain Pattern Analysis
Bloodstain pattern analysis (BPA) is a forensic discipline focused on analyzing Blood residue, bloodstains left at known, or suspected crime scenes through visual pattern recognition and physics-based assessments. This is done with the purpose of drawing inferences about the nature, timing and other details of the crime. At its core, BPA revolves around recognizing and categorizing bloodstain patterns, a task essential for reconstructing events in crimes or accidents, verifying statements made during investigations, resolving uncertainties about involvement in a crime, identifying areas with a high likelihood of offender movement for prioritized DNA sampling, and discerning between homicides, suicides, and accidents. Since the late 1950s, BPA experts have claimed to be able to use biology, physics, and mathematical calculations to reconstruct with accuracy events at a crime scene, and these claims have been accepted by the criminal justice system in the US.

Scientific Working Group
Since the early 1990s, American and International forensic science laboratories and practitioners have collaborated in Scientific Working Groups (SWGs) to improve discipline practices and build consensus standards. In 2014, the SWGs are being reorganized under the NIST Organization for Scientific Area Committees (OSAC). As of January 2012, active SWGs included the following: * FISWG - Facial Identification Scientific Working Group * SWGANTH - Forensic Anthropology * SWGCBRN - Chemical, Biological, Radiological and Nuclear * SWGDAM - DNA Analysis * SWGDE - Digital Evidence * SWGDMI - Medicolegal Death Investigation * SWGDOC - Questioned Documents * SWGDOG - Dogs and Orthogonal Detection * SWGDRUG - Analysis of Seized Drugs * SWGDVI - Disaster Victim Identification * SWGFAST - Latent Fingerprints * SWGFEX - Fire and Explosives Scenes * SWGGEO - Geological Materials * SWGGSR - Gunshot Residue * SWGGUN - Firearms and Toolmarks * SWGIBRA - Illicit Business Records * SWGIT - Ima ...

Daubert Standard
In United States federal law, the ''Daubert'' standard ( ) is a rule of evidence regarding the admissibility of expert witness testimony. A party may raise a ''Daubert'' motion, a special motion ''in limine'' raised before or during trial, to exclude the presentation of unqualified evidence to the jury. The ''Daubert'' trilogy are the three United States Supreme Court cases that articulated the ''Daubert'' standard: *'' Daubert v. Merrell Dow Pharmaceuticals, Inc.'' (1993), which held that Rule 702 of the Federal Rules of Evidence did not incorporate the ''Frye'' standard as a basis for assessing the admissibility of scientific expert testimony, but that the rule incorporated a flexible reliability standard instead; *'' General Electric Co. v. Joiner'' (1997), which held that a district court judge may exclude expert testimony when there are gaps between the evidence relied on by an expert and that person's conclusion, and that an abuse-of-discretion standard of review is the pro ...

Forensics Organizations
Forensic science combines principles of law and science to investigate criminal activity. Through crime scene investigations and laboratory analysis, forensic scientists are able to link suspects to evidence. An example is determining the time and cause of death through autopsies. This evidence can then be used for proof towards a crime. Forensic science, often confused with criminalistics, is the application of science principles and methods to support legal decision-making in matters of criminal and civil law. During criminal investigation in particular, it is governed by the legal standards of admissible evidence and criminal procedure. It is a broad field utilizing numerous practices such as the analysis of DNA, fingerprints, bloodstain patterns, firearms, ballistics, toxicology, microscopy, and fire debris analysis. Forensic scientists collect, preserve, and analyze evidence during the course of an investigation. While some forensic scientists travel to the scene of the ...

Government Agencies Established In 2002
A government is the system or group of people governing an organized community, generally a state. In the case of its broad associative definition, government normally consists of legislature, executive, and judiciary. Government is a means by which organizational policies are enforced, as well as a mechanism for determining policy. In many countries, the government has a kind of constitution, a statement of its governing principles and philosophy. While all types of organizations have governance, the term ''government'' is often used more specifically to refer to the approximately 200 independent national governments and subsidiary organizations. The main types of modern political systems recognized are democracies, totalitarian regimes, and, sitting between these two, authoritarian regimes with a variety of hybrid regimes. Modern classification systems also include monarchies as a standalone entity or as a hybrid system of the main three. Historically prevalent for ...
