ABSTRACT
INTRODUCTION You are a juror in a case involving serious assault. You are finding it very hard to decide whether the defendant is indeed the person who carried out the assault. This is because nearly all the evidence is indirect or circumstantial, and so not really very convincing. However, one piece of evidence does seem to be very direct and revealing. The person who was assaulted identified the defendant as her assailant in a lineup. When you see this eyewitness being questioned in court, you are impressed by the fact that she is very confident that she has correctly identified the person who attacked her so viciously. As a result, you and your fellow jurors find the defendant guilty of serious assault and he is sentenced to several years in prison.
