What potential improvements could be made as to how line ups and photo spreads can be used differently in investigations in an effort to reduce misidentification?

The 1998 us attorney generals report on “best practices” in photo identification and the recent efforts and suggestions of the innocence project is important to consider when examining the issues related to suspect identification.
Four rules suggested by the attorney general include:-the person who conducts the lineup or photo spread should not be aware of which member of the lineup or photo spread is the suspect.-eyewitnesses should be told explicitly that the person on question might not be in the lineup or photo spread and therefore should not feel that they must make an identification. They should also be told that the person administrating the lineup does not know which person is the suspect in the case.-the suspect should not stand out in the lineup or photo spread as being different from the distractors based on the eyewitness previous description of the culprit or based on other factors that would draw extra attention to the suspect.-a clear statement should be taken from the eyewitness at the time of the identification and prior to any feedback as to his or her confidence that the identified person is the actual culprit.
