"Although no hard and fast rules to the manner a trial judge should determine questions of disputed identity, it seems clear to us that he could not be said to have properly resolved the issue unless there is shown in a record a careful and considered analysis of all the surrounding circumstances of the crime being tried. We would, for example, expect to find in record questions as the following posted and resolved by him; the time the witness had the accused under observation; the distance at which he observed him; the conditions in which such observations occured, for instance, whether it was day or night-time, whether that was good or poor lighting at the scene; and further whether the witness knew or had seen the accused before or not. These matters are but a few of the matters to which the trial judge should direct his mind before coming to any definite conclusion on the issue of identity".
