Manson v. Brathwaite432 U.S. 98 (1977)

(1)Was the procedure “unnecessarily suggestive”

Social Science Research • State v. Henderson, 2011 WL 3715028

(N.J. 2011) – “The research . . . represents the ‘gold standard in terms of the applicability of social science research to the law.’”

• Three stages of remembering

– acquisition, retention, retrieval

• System Variables –identification procedures

• Estimator Variables (lighting, weapon focus, distance, duration, memory decay, stress, witness characteristics, cross-race)

A Line-Up

12

The Eyewitnesses• I studied 160 exoneree trial transcripts• 84% involved a rape and testimony of the

victim• 68 were identified by multiple

eyewitnesses (36% of 190 cases)• 48% (92 of all 190 cases) involved a

cross-racial identification.• In 67 of those cases, white women

misidentified black men.• 12% of the cases (22 of all 190) involved

child eyewitnesses

13

Suggestion and Unreliability• 78% (124 of 160 cases with transcripts)

involved suggestive techniques

• 57% (91 of 160 cases with transcripts) involved witnesses who were initially not certain of their identification.

14

Types of identifications

• 117 exonerees were identified in a photo array

• 60 were identified in a line-up

• 53 were identified in a show-up

• 45 cases involved composite drawings

System Variables: Best Practices

• Blind identifications

• Sequential identifications

• Confidence statements

• Instructions

• Lineup Composition

Regulating ID’s in the Courtroom

• State v. Henderson, 2011 WL 3715028 (N.J. 2011)– Pre-trial hearings– Reliability factors grounded in social science– Detailed jury instructions

• Virginia - “Independent source” rules

• Admissibility of expert testimony
