Forensic Science. Jim Fraser287 руб
What happens at a crime scene? How does DNA profiling work? How can it help solve crimes that happened 20 years ago? In forensic science, a criminal case can often hinge on a piece of evidence such as a hair, a blood trace, half a footprint, or a tyre mark. Forensic science is a subject of wide fascination. However, the public understanding of forensic science is poor, and largely based on TV shows such as CSI: Crime Scene Investigation, which exploit high-tech imagery for dramatic effect. High profile cases such as the Stephen Lawrence enquiry and the Madeleine McCann case have attracted enormous media attention and enhanced this interest in recent years. However, it also deals with real life issues and its results are interpreted within unique situations. Forensic science is a complex activity at the interface of science and law. In this Very Short Introduction, Jim Fraser introduces the concept of forensic science and explains how it is used in the investigation of crime. Complex scientific findings must be considered carefully, dispassionately, and communicated with clarity, simplicity, and precision. He explores how forensic scientists work; from the reconstruction of events to laboratory examinations. He begins at the crime scene itself, explaining the principles and processes of crime scene management. Providing examples from forensic science cases in the UK, US, and other countries, he considers the techniques and challenges faced around the world. He considers the techniques they use, such as fingerprinting, and goes on to highlight the immense impact DNA profiling has had. Из серии: Very Short Introductions (Oxford University Press) 2010 |
