what is forensic science?

Blood drop (Richard Jones 2015)


Forensic science is the application of scientific principles to questions of forensic (or legal) importance. Any branch of science may be of assistance in answering those questions, but of particular importance are:

In any legitimate justice system, ... truth must play a paramount and integral role... The very survival of the rule of law depends not only on a justice system that administers the law fairly, but a system that is just by being well-grounded in ... truth ...[M]ore research is needed in the techniques and science already in use. With the importance of forensic science to truth and justice, the science employed and relied upon by judges and juries must be valid. It does not matter how well forensic scientists abide by testing protocols, or how reliable the techniques are, if the underlying science does not actually reveal what the expert says it does. Method validation studies and new research must be on-going even in the area of traditional forensic disciplines.

forensic science in action - Stephen Lawrence murder


18-year-old teenager, Stephen Lawrence, was murdered by a gang of racist youths in Well Hall Road, Eltham, South London on 22nd April 1993. Two members of that gang, Gary Dobson and David Norris, were convcted of his murder on 3rd January 2012.


Stephen had been stabbed to a depth of about five inches on both sides of the front of his body to the chest and arm. Both stab wounds severed axillary arteries, and blood must literally have been pumping out of and into his body as he ran up the road to join his friend. In the words of Dr Shepherd, the pathologist, "It is surprising that he managed to get 130 yards with all the injuries he had, but also the fact that the deep penetrating wound of the right side caused the upper lobe to partially collapse his lung. It is therefore a testimony to Stephen's physical fitness that he was able to run the distance he did before collapsing".

And watch the evidence of Jeremy Brown MP to the Committee at a 'follow-up' session, in which he appears to struggle to describe what the Government strategy is now for the future provision and development of forensic science in England and Wales, save for the devolvement of forensic science to private providers.
