NARRATOR MALE
Following his full description of the unmasked robber, will Andrew be able to identify him?
ANDREW
Hiya
NARRATOR MALE
Strict protocols are followed to ensure the witnesses aren't influenced. The line-up must be viewed twice, then if required, any numbers can be called up again.
ANDREW
Number 1 and number 3 I'd like to see again
OFFICER
Number 1 and 3?
OFFICER
Was the person shown the film?
ANDREW
Yes, number 3.
OFFICER
In order to confirm your identification, is this the person you were referring to when you made the ID?
ANDREW
Yes.
SIMON
Would I recognise him again? Yeah. If I saw him I would say, yeah, I could say "that's definitely him". I got quite a good clear view of him because he actually looked straight at me.
NARRATOR MALE
Is Simon still as confident?
OFFICER
Was the person shown on the film?
SIMON
Yeah I couldn't be sure.
OFFICER
Can't be sure.
SIMON
No.

DS Sund used a VIPER parade with Lila and Seth. VIPER parades involve presenting a sequence of clips, one after the other, that show a head and shoulders view of the suspect and foils. Each person is shown looking straight at the camera and then turning from side to side so that their face can be seen from multiple angles. The images are carefully controlled so that the background, lighting, etc. are identical, and foils can be chosen from a large database containing more than 25,000 possible people. Research has shown that this makes such parades ‘fair’, in that there is nothing that makes the suspect stand out, and the foils look suitably similar to the suspect.
