The forensic science investigation of a criminal case is a complex process. Briefly, it begins with the assembly of the correct “tools” properly validated for their defined use and processes to the deployment of properly trained and accredited personnel who investigate the crime scene. Most of these personnel are under the control of the police forces as scenes of crime officers (SOCO’s) or crime scene investigators (CSI’s) but especially in serious crimes some of the personnel will be laboratory based scientists. Where items are found and by whom are recorded and then appropriately packaged and securely transported to either a forensic science laboratory or a police station with its own small laboratory for preliminary screening. These latter laboratories may or may not be accredited by the United Kingdom Accreditation Service (UKAS). All major forensic science laboratories, whether directly controlled through the Home Office ie The Forensic Science Service (FSS), or commercially independent such as LGC-Forensics, Cellmark, Key Forensics, must be accredited under UKAS if they are to present evidence to the courts for the prosecution. Compliance with the accreditation is monitored by the Forensic Science Regulator. The Regulator also has a role in producing manuals of best practice. Of vital importance both at the scene, during transportation and within the laboratory are measures to prevent contamination and cross contamination. This process is a costly one and compliance with legal requirements means that it can also become a stressful one associated with the need to meet time deadlines. 2. There is a misconception that forensic science is simply a series of independent .tests. For example, a test on a stain on a garment to determine if it is blood, followed by a DNA test on the cut out stain to determine the origin of the blood. Such tests can be itemised and costed appropriately. Moreover, if the first test is carried out in the police laboratory it will reduce costs to that police force. The problem with such an approach is that while the profile of the DNA may be obtained, the scientist conducting the test will find it difficult and sometimes impossible to interpret the meaning of his findings in the context of the case. This would be exacerbated if there is additional scientific evidence to be woven into the tapestry of the case such as a blood stained footwear mark at the scene to be matched with all, rather than some, of the footwear recovered from suspects. It is not unknown, on the basis of cost, for only selected footwear to be sent to the laboratory.
