Simultaneous display of photos (usually 6)

Lineup created and presented by investigator who knows who suspect is

“Blind”- administrator of test does not know who the suspect is

“Blinded” - administrator knows who suspect is but test is administered in such a manner that administrator cannot see which photo W is viewing; W knows administrator does not know order

“Nonblind” – administrator knows who suspect is and can see which photo W is viewing; W knows administrator knows who suspect is

W wants to help & will look to investigator for cues (especially if good rapport)

Even most experienced professional who knows ID of suspect cannot eliminate possibility of unintentional cues

Simultaneous display encourages picking the person who looks most like perpetrator (regardless of whether it is the perpetrator)

Picking the person who looks most like the perpetrator is 100% wrong if real perpetrator is not in

lineup. This is what happened in DNA exonerations.

Blind administration eliminates this as an issue

Sequential photo display

Blind or blinded administration

Someone other than an investigator who knows the identity of the suspect shows the lineup

If only investigator who knows ID of suspect is available to do lineup, he must

do so in a manner that ensures he does not know and cannot see where suspect is

Number photos and folders (do not make suspect # 1); insert photo in folder with same number

If blind administrator is available, investigator who knows suspect ID may prepare folders

Otherwise, someone other than investigator who shows lineup must prepare folders (another investigator or even a civilian employee); this is the blinded procedure

Person who committed crime may or may not be included I do not know if any person being investigated is included

(blind) or I do not know the order of photos (blinded) I will continue to show you all photos even if you ID

someone A photo may be an old one; some things like hair style

may change; skin tones may look different in photos Do not feel you have to make an ID; it is just as important

to clear innocent as ID guilty; investigation will continue regardless

You will see only 1 photo at a time; they are in no particular order; take as much time as you need

Do not discuss procedure with any other W

Show only one photo at a time; remove from view before next photo is shown

After W has looked at each photo, ask “Is this the person who [describe act]?”

If no, go to next photo and repeat If yes, ask “How certain are you of your

selection?” Continue showing rest of photos Note all comments W makes on any photo If W asks for repeat, show all photos (in

same order) Keep track of number of cycles

Preserve copy of photos shown in order (simultaneous 6-pack template works well)

If ID made, have W sign photo picked Report should include:

◦Whether blind or blinded method used◦Instructions given to W◦Results of lineup◦If ID made, answer to level of certainty Q
