As Forensic science is defined as the application of science and its principles to the law and justice system. Both prosecution and defence can call on the same or differing Forensic Evidence in trial. Evidence is usually findings or opinions presented as formal statements or reports. All Forensic Evidence is subject to the rules and regulations of The Police and Criminal Evidence Act 1984.
Forensic science is usually used in the examination of physical traces i.e. hair, blood which can help establish a link between a victim/scene of crime and a criminal. Yet others can specialise in firearms, explosives, and provide insight into the cause of a fire or a road accident. On occasion Forensic scientist will visit a crime scene in person to assist investigators in piecing together a sequence of events based on physical evidence such as blood patterns or gunpowder residue.
Other forensic scientists will be able to scrutinise drug/alcohol abuse and/or poisoning. This course will teach you why continuity and the chain of evidence is so important in trials and convictions.
