Abstract
A forensic science laboratory is scientific laboratory specializing in forensic science. Such laboratories maybe run by private companies or the government but are often associated with the law enforcement infrastructure of a country. Its functions are to examine, compare and evaluate physical evidence so as to link a suspect to the victim or to the scene of a crime. In most cases, the laboratory supplements the work of police investigator in order to convert suspicion into a reasonable certainty of either guilt or innocence. Protection of the innocent example of person arrested for selling narcotics is set free if the chemical analysis of the material shows it to be harmless. It determines facts, which are not subject to the bias and Prejudice & other human failings of the eye witness. Training of the police investigators as to what constitutes physical evidence, how it is to be found, collected, reserved and delivered to the laboratory. It is not a solution for all the difficulties that confront the police in searching out crime; it is merely an aid in crime detection.Its results are more often rather negative than positive. The items which are most commonly handled by the laboratory and which frequently serve as evidence knives, blunt instruments, blood &seminal stains, chemical substances, poisons, fingerprints & footprints, hair,fibers, bullets,cartridge cases and wad, tools & tool marks, broken glass, paint chips, oil, grease, petroleum products,soils, clothing, pieces of paper, cigars, cigarette stumps, matches, documents & fragments of various materials.Sometimes laboratory technicians are called to the scene of crime to collect specimens with which investigating officersare not qualified to deal.
