Ethics in forensic science: Professional standards for the practice of criminalistics.

Many commentators have acknowledged the fact that the usual courtroom maxim that is “to tell the truth, the whole truth, and nothing but the truth” is not so easy to apply in practicality. In any given situation, what does the whole truth includes? In case the whole truth includes all the possible alternatives for a given situation, what should a forensic expert witness do when an important question is not asked by the prosecutor? Does the obligation to tell the whole truth mean that all possible, all probable, all reasonably probable, all highly probable, or only the most probable alternatives must be given in response to a question? (Barnett 2001).
Due to the absence of any regulatory organization, forensic science has no official recognition or registration that should provide certain rights and responsibilities to forensic scientists. In forensic science, individuals from various fields with adequate qualifications are employed without any statutory certification or registration. The only possible restraint upon professional misconduct of a forensic scientist is through membership of such a craft organization (Knight 1989). Therefore, there is an immense need to establish these codes, but this doesn’t mean that they can never be changed; on the contrary, they should be revised regularly from time to time to meet the growing demands of maintaining standards of forensic laboratories.
