A legal analysis of the study of the scientific evidence of Deoxyribonucleic Acid (DNA)

Abstract

This study analyses how DNA evidence can be distorted by the behaviour of criminal investigators and role-players within the Criminal Justice System (CJS). This has a negative impact on justice resulting in further criminality. The study has resulted in revelatory weaknesses owing to constitutional violations which cause sound evidence to become futile as it will not be admissible in court. Justice is aborted. The researcher has further explained the properties of the pertinent terms, such as: mental illness, psycho-social functioning, DNA, forensic investigator, forensic psychology, and courts. Concepts are building blocks, hermeneutical distortion leads to the frustrating of what justice intends and this, in turn, leads to poor criminal investigation performance. It is submitted that not only ineptness, but also deception possibly evolves from genotypic to phenotypic type which causes unwelcome behaviour within the criminal justice system to surface. The frequency of monitoring psychological behaviour amongst criminal investigations is low, and it, therefore, also contributes to delict and the miscarriage of justice occurs.
