The science of forensics and the crime investigation lab have become an increasingly important aspect of police work. This brand-new Easy Way title introduces criminology students and law enforcement candidates to forensics in four major sections: Introduction to Forensic Science, The Physical Sciences, Physical Evidence, and The Future of Forensic Science. Among the topics explored are applications of the sciences of physics and chemistry to forensics, physical evidence, body fluids, explosives and incendiaries, firearms, fingerprints, DNA evidence, and many more. Discussion of future trends includes retinal scans and other ID systems, computer databases and searches, and more. Review questions with answers appear at the end of each chapter. Barron's Easy Way books introduce a variety of academic and practical subjects to students and general readers in clear, understandable language. Ideal as self-teaching manuals for readers interested in learning a new career-related skill, these books have also found widespread classroom use as supplementary texts and brush-up test-preparation guides. Subject heads and key phrases that need to be learned are set in a second color.
