Chief Dekmar’s claim that proposals to require police to conduct
sequential (as opposed to simultaneous) lineups are “based on erroneous
or faulty research” is dead wrong. Overwhelmingly, the scientific
literature demonstrates the superior reliability of the sequential
lineup.
Chief Dekmar’s article evinces minimal comprehension of the focal point
of the suggested law–the problem of convictions of innocent
persons. Since the 1930s, mistaken eyewitness identification has
been acknowledged as the principal reason why innocent persons are
sometimes convicted. Three-quarters of the over 200 persons
exonerated by DNA evidence in recent years (including all 6 of
Georgia’s DNA exonerees) were the victims of eyewitness
misidentification.
These misidentifications nearly always stemmed from suggestive
police identification procedures, which police do not videotape but
conduct under circumstances of secrecy and in defiance of numerous
scientific studies demonstrating that these procedures are apt, whether
intentionally or not, to result in mistaken eyewitness testimony
harmful to an innocent accused.
Police routinely ignore the dangers of what psychologists call the
Experiment Expectancy Effect by suggesting to the witness, usually
covertly, which suspect they want identified or which suspect they
think the witness should have identified. If the police are in
fact wrong about whether that suspect is guilty, their conduct may have
the effect of erasing the witness’ previous memory, with the result
that the witness actually comes to believe in good faith that his or
her identification, although in actuality mistaken, is reliable.
And when police display confidence in this mistaken identification, the
result is the Confidence Malleability Effect–the tendency of the
eyewitness to enhance his or her confidence that the misidentification
was correct, making it extremely likely that a trial jury will convict.
The passing reference Chief Dekmar’s article makes to erroneous
convictions resulting from mistaken eyewitness testimony in Georgia is
the laconic observation that these “tragic cases ... involve
misidentifications ... 15 to 20 years old.” Yet noticeably
he makes no showing that police identification procedures have
significantly improved during the last 20 years, and he gives us little
reason to doubt that, absent reform legislation, in 20 years we will
learn of wrongful convictions resulting from the unfair identification
procedures that continue today.
If a law enforcement spokesman displays so little concern about the
plight of innocent persons who have been or will be imprisoned due to
defective police identification practices, can we have confidence that
police, acting on their own, will ever correct their own practices?
Chief Dekmar’s article is full of feel-good generalizations about what
the police, acting on their own, “should” do to improve their
identification procedures. The question, however, is not what
they should do, but why they didn’t do it long ago. The
scientific evidence concerning the defects in police identification
procedures has been around for over thirty years. Convictions of
innocent persons due to these defects have continued to occur.
Yet, as the Atlanta Constitution reported last month, 83% of 293
Georgia police agencies responding to a Georgia Innocence Project
questionnaire “have no specific guidelines governing the collection of
eyewitness evidence.” Furthermore, 130 other Georgia police
agencies failed to respond when asked whether they had such guidelines.
Georgia should follow the example other states that have recently
enacted laws to reform the way police conduct lineups. The North
Carolina legislation, enacted last August, should be the model for
Georgia. It requires sequential lineups of individuals or photos;
sets forth other specific procedures relating to the content and
conduct of lineups; and requires that training and educational
materials explaining the new statute be provided to police.
Experience shows that unfortunately Georgia police will not, if left to
themselves, cease engaging in practices that unnecessarily increase the
possibility that innocent persons will be convicted, imprisoned, and
even executed. Therefore they must be compelled to do so by
statute.
