An identification after seeing a person's entire face is itself a difficult task. The initial process of seeing a perpetrator and capturing a memory may be impaired by a multitude of factors—the presence of a weapon, high stress, poor lighting, whether the witness and perpetrator are of different races, the duration of observation and possible post-event memory contamination. But at least some facial identifications are reliable (see, e.g., familiar identifications of a previously well-known individual). The question is—can the same be said when the perpetrator was fully masked and all that was visible were his eyes?
