Since the 1960s, testimony by representatives of the Federal Bureau of Investigation in thousands of criminal cases has relied on evidence from Compositional Analysis of Bullet Lead (CABL), a forensic technique that compares the elemental composition of bullets found at a crime scene to the elemental composition of bullets found in a suspect s possession. Different from ballistics techniques that compare striations on the barrel of a gun to those on a recovered bullet, CABL is used when no gun is recovered or when bullets are too small or mangled to observe striations. Forensic Analysis:[more]
Two members of the Committee on Human Rights (CHR), NAS member Mary Jane West-Eberhard and NAS/NAE member Morton Panish, undertook a mission to Guatemala to observe the trial of two high-level Guatemalan military officials who were charged with ordering the murder of Guatemalan anthropologist Myrna Mack. She was stabbed to death in 1990, two days after a report for which she was principal researcher, Assistance and Control: Policies Toward Internally Displaced Populations in Guatemala, was published by the Georgetown University Press. Ms. Mack had been doing research on and writing about t
The polygraph, often portrayed as a magic mind-reading machine, is still controversial among experts, who continue heated debates about its validity as a lie-detecting device. As the nation takes a fresh look at ways to enhance its security, can the polygraph be considered a useful tool?
The Polygraph and Lie Detection puts the polygraph itself to the test, reviewing and analyzing data about its use in criminal investigation, employment screening, and counter-intelligence.
The book looks at:
The theory of how the polygraph works and evidence about how deceptivene
Most major crime in this country emanates from two major data sources. The FBI s Uniform Crime Reports has collected information on crimes known to the police and arrests from local and state jurisdictions throughout the country. The National Crime Victimization Survey, a general population survey designed to cover the extent, nature, and consequences of criminal victimization, has been conducted annually since the early1970s. This workshop was designed to consider similarities and differences in the methodological problems encountered by the survey and criminal justice research communities an
How should the war on drugs be fought? Everyone seems to agree that the United States ought to use a combination of several different approaches to combat the destructive effects of illegal drug use. Yet there is a remarkable paucity of data and research information that policy makers require if they are to create a useful, realistic policy package-details about drug use, drug market economics, and perhaps most importantly the impact of drug enforcement activities.
Informing America's Policy on Illegal Drugs recommends ways to close these gaps in our understanding-by obtaining
Even though youth crime rates have fallen since the mid-1990s, public fear and political rhetoric over the issue have heightened. The Columbine shootings and other sensational incidents add to the furor. Often overlooked are the underlying problems of child poverty, social disadvantage, and the pitfalls inherent to adolescent decisionmaking that contribute to youth crime. From a policy standpoint, adolescent offenders are caught in the crossfire between nurturance of youth and punishment of criminals, between rehabilitation and "get tough" pronouncements. In the midst of this emotional debate,
This workshop arose out of the efforts of the Committee on Law and Justice to assist the National Institute of Justice in identifying gaps in the overall research portfolio on crime and justice. It was designed to develop ideas about the kinds of knowledge needed to gain a better understanding of the prosecution function and to discuss the past and future role of social science in advancing our understanding of modern prosecution practice. The Committee on Law and Justice was able to bring together senior scholars who have been working on this subject as well as current or former chief pros
