Prosecutor: Dr  Yuge has testified that, had the robbery occurred after 1: 50 A  M  , then, the moon having set at 1: 45 A  M  , it would have been too dark for Klein to recognize the perpetrator  But Yuge acknowledged that the moon was full enough to provide considerable light before it set  And we have conclusively shown that the robbery occurred between 1: 15 and 1: 30 A  M
So there was enough light for Klein to make a reliable identification
Without having been there, Dr. Yuge has no way of knowing whether the light was sufficient.
