There is no doubt that a confessional statement is the best evidence to prove a crime. It is the evidence of the perpetrator describing why and how the crime was committed. It proves both the mens rea and the actus reus. However, such admission to be solely used to convict a defendant must be voluntarily made and must be a positive and direct admission of guilt.
