Cases which have eyewitness testimony have a higher probability of producing convictions (Visher, 1987). Jurors are doubtful of the eyewitnesses with low memory regarding details whereas they might be more accurate owing to the fact that they were concentrating on the face of the culprit instead (Wells & Leippe, 1988).
