Few law enforcement institutions
have been so thoroughly discredited in recent years as the FBI’s
forensic lab. In 1997 the Bureau’s inspector general of the time issued a
devastating report, stigmatizing one instance after another of
mishandled and contaminated evidence, inept technicians, and outright
fabrication. The IG concluded that there were "serious and credible
allegations of incompetence" and perjured courtroom testimony.
CounterPunch’s
view is that taken as a whole, forensic evidence as used by prosecutors
is inherently untrustworthy. For example, for years many people went to
prison on the basis of the claims of a North Carolina anthropologist,
Louise Robbins. She helped send people to prison or to Death Row with
her self-proclaimed power to identify criminals through shoe prints. As
an excellent recent Chicago Tribune series on forensic humbug recalled,
on occasion she even said she could use the method to determine a
person’s height, sex and race. Robbins died in 1987, her memory
compromised by the conclusion of many Appeals Courts that her
methodology was bosh. There have been similarly hollow claims for lip
prints and ear prints, all of (added "of") them invoked by their
supporters as "100 per cent reliable" and believed by juries too easily
impressed by passionate invocations to 100 per cent reliable scientific
data.
Of course the apex forensic hero of prosecutors, long
promoted as the bottom line in reliability–at least until the arrival of
DNA matching–has been the fingerprint.
Fingerprints entered the
arsenal of police and prosecutors in the late nineteenth century, touted
as "scientific" in the manner of other fashionable methods of that time
in the identification of supposed criminals, such as phrenology. A
prime salesman was Francis Galton, Charles Darwin’s cousin and a
founding huckster for the bogus "science " of eugenics. Actually
fingerprints, at least in modern times, found their original use in the
efforts of a British colonial administrator to intimidate his Indian
laborers (whose faces he could not distinguish) from turning up more
than once to get paid. He’d make a great show of scrutinizing the
fingerprints he insisted they daub on his ledger book. Then, as now, the
use of the so-called "unique fingerprint" has been histrionic , not
scientific. In 1995, so the Chicago Tribune series discovered, " one of
the only independent proficiency tests of fingerprint examiners in U.S.
crime labs found that nearly a quarter reported false positives, meaning
they declared prints identical even though they were not–the sort of
mistakes that can lead to wrongful convictions or arrests."
Decade
after decade people have been sent to prison for years or dispatched to
the death cell, solely on the basis of a single, even a partial print.
So great is the resonance of the phrase "a perfect match" that defense
lawyers throw in the towel, as judge and jury listen to the assured
conclusions of the FBI’s analysts who virtually monopolize the
fingerprint industry in the U.S.A. Overseas, in London’s Scotland Yard
for example, the same mesmerizing "certainty" held sway, and still does.
In the U.S.A., part of the mystique stems from the "one discrepancy
rule" which has supposedly governed the FBI’s fingerprint analysis. The
rule says that identifications are subject to a standard of "100 per
cent certainty" where a single difference in appearance is supposed to
preclude identification.
The 1997 lab scandals threw a shadow
over the FBI’s forensic procedures as a whole and the criminal defense
bar began to raise protests against prosecutorial use of latent
fingerprint identification evidence, as produced by FBI procedures. In
2002 Judge Louis Pollak, in a case in Pennsylvania, initially ruled that
the FBI’s fingerprint matching criteria fell below new standards of
forensic reliability (the Daubert standards) stipulated by the U.S.
Supreme Court. Ultimately he was persuaded that the FBI’s fingerprint
lab had never made a mistake. In 2004, in U.S. v. Mitchell, the Third
Circuit Court of Appeals upheld these same procedures.
Now at
last, in 2006, the FBI’s current inspector general, Glenn Fine, has
grudgingly administered what should properly be regarded as the
deathblow to fingerprint evidence as used by the FBI and indeed by law
enforcement generally.
The case reviewed by Inspector General
Fine, at the request of U.S. Rep John Conyers and U.S. Senator Russell
Feingold, concerns the false arrest by the FBI of Brandon Mayfield, a
lawyer from Beaverton, Oregon.
On March 11, 2004, several bombs
exploded in Madrid’s subway system with 191 killed and 1,460 injured.
Shortly thereafter the Spanish police discovered a blue plastic bag
filled with detonators in a van parked near the Acala de Heres train
station in Madrid, whence all of the trains involved in the bombing had
originated on the fatal day.
The Spanish police were able to lift
a number of latent prints off the bag. On March 17 they transmitted
digital images of these fingerprints to the FBI’s crime lab in Virginia.
The lab ran the images through its prized IAFIS, otherwise known as the
integrated, automated, fingerprint identification system, containing a
database of some 20 million fingerprints.
The IAFIS computer spat
out twenty "candidate prints", with the warning that these 20
candidates were "close non-match". Then the FBI examiners went to work
with their magnifying glasses, assessing ridges and forks between the
sample of 20 and the images from Spain. In a trice the doubts of the
IAFIS computer were thrust aside, and senior fingerprint examiner Terry
Green determined that he had found "a 100 per cent match" with one of
the Spanish prints of the fourth-ranked print in the IAFIS batch of 20
close non-matches. Green said this fourth ranked print came from the
left index finger of Brandon Mayfield. Mayfield’s prints were in the
FBI’s master file, not because he had been arrested or charged with any
crime, but because he was a former U.S. Army lieutenant.
Green
submitted his conclusions to two other FBI examiners who duly confirmed
his conclusions. But as the inspector general later noted, these
examiners were not directed to inspect a set of prints without knowing
that a match had already asserted by one of their colleagues. They were
simple given the pair of supposedly matched prints and asked to confirm
the finding. (These two examiners later refused to talk to the FBI’s
inspector general.)
The FBI lost no time in alerting the U.S.
Prosecutor’s office in Portland, which began surveillance of Mayfield
with a request to the secret FISA court which issued a warrant for
Mayfield’s phone to be tapped on the grounds, laid out in the Patriot
Act, that he was a terrorist, and therefore by definition a foreign
agent.
Surreptitious tapping and surveillance of Mayfield began.
On April 2, 2004, the FBI sent a letter to the Spanish police informing
them that they had a big break in the case, with a positive
identification of the print on the bag of detonators.
Ten days
later the forensic science division of the Spanish national police sent
the FBI its own analysis. It held that the purported match of Mayfield’s
print was "conclusively negative". (The inspector general refers to
this as the "negativo Report".)
The next day, April 14, the U.S.
Prosecutor in Portland became aware of the fact that the Spanish
authorities were vigorously disputing the match with Mayfield’s left
forefinger. But by now the Prosecutor and his team were scenting blood.
Through covert surveillance they had learned that Mayfield was married
to an Egyptian woman, had recently converted to Islam, was a regular
attendee at the Bailal mosque in Portland, and had as one of his clients
in a child custody dispute an American Muslim called Jeffrey Battle.
Battle, a black man, had just been convicted of trying to go to
Afghanistan to fight for the Taliban.
Armed, so they thought,
with this arsenal of compromising detail, the U.S. Prosecutor and the
FBI had no patience with the pettifogging negativism of the Spanish
police. So confident were the Americans of the guilt of their prey that
they never went back to take another look at the supposedly matching
prints. Instead, on April 21, they flew a member of the FBI’s latent
print unit to Spain for on-the-spot refutation of the impertinent Madrid
constabulary.
The Inspector General’s report makes it clear that
the FBI man returned from Spain with a false account of his reception,
alleging that the Spanish fingerprint team had bowed to his superior
analytic skills. The head of the Spanish team, Pedro Luis Melida-Weda,
insists that his team remained entirely unconvinced. "At no time did we
give our approval. We refused to validate the FBI’s conclusions. We kept
working on the identification."
By now either the U.S.
Attorney’s office or, more likely, the FBI was leaking to the press news
of the pursuit of a U.S. suspect in the Madrid bombing. But they knew
that the actual evidence they had on Mayfield was virtually
non-existent, aside from the fingerprint. On May 6, the U.S. Prosecutor
in Portland told U.S. District Court Judge Robert Jones that the Spanish
police had ultimately accepted the FBI’s match, that Mayfield, alerted
by the stories in the press about an unnamed suspect, might start
destroying evidence, and that, therefore, they wanted to seize Mayfield,
using the now favored charge du jour of the war on terror, claiming him
to be a "material witness". Judge Jones okayed an arrest warrant.
Mayfield
had no idea that the FBI had been tapping his phones and secretly
rummaging through his office. The first time he became aware that he was
a citizen under suspicion was on the afternoon of May 6. On that day
eight FBI agents showed up at his law office, seized him, cuffed his
hands behind his back, ridiculed his protestations. As they approached
the door, Mayfield implored them to take the handcuffs off, saying he
didn’t want his clients or staff to see him in this condition. The FBI
agents said derisively, "Don’t worry about it. The media is right behind
us."
Mayfield ended up with two federal public defenders, Steven
Wax and Christopher Schatz. Like many such, these two were dedicated to
their interest of their client, tireless and resourceful. Their first
concern was to get Mayfield out on the Multnomah federal detention
center in downtown Portland. Though jailed under an alias chosen for him
by the U.S. Prosecutor, the feds had immediately leaked this
alias–Randy Barker–to The Oregonian newspaper, and a guard at the jail
had promptly roughed up Mayfield.
The two public defenders went
before Judge Jones and asked that as a material witness he be kept under
house arrest, there being scant apparent evidence against him. Judge
Jones finally compelled the U.S. Prosecutor to say what evidence he had
against Mayfield. A fingerprint, said the U.S. Prosecutor, withholding
from the court the fact that this fingerprint was highly controversial
and had been explicitly disqualified by the Spanish police.
The
federal defenders questioned the imprisonment of their client, faced
penalties of the utmost gravity, on the basis of a fingerprint. Judge
Jones allowed as how he had sent people to prison for life on the basis
of a single fingerprint. Mayfield’s attorneys asked to see a copy of the
allegedly matched fingerprints and have them evaluated by their own
expert witness. Knowing he was on thin ice the U.S. Prosecutor refused,
claiming it was an issue of national security. Under pressure from Judge
Jones, himself pressured by the assiduous federal defenders, the U.S.
Prosecutor finally agreed he would give the prints to an independent
evaluator selected by Judge Jones.
The prints were given to
Kenneth R. Moses of San Francisco, an SFPD veteran who runs a company
called Forensic Identification Services which, among other things,
proclaims its skills in "computer enhancement of fingerprints". It was
"quite difficult", Moses said, because of "blurring and some blotting
out", but yes, the FBI had it right, and there was "100 per cent
certainty" that one of the prints on the blue bag in Madrid derived from
the left index finger of Brandon Mayfield.
Moses transmitted
this confident opinion by phone to Judge Jones on the morning of May 19.
Immediately following Moses’ assertion, the U.S. attorney stepped
forward to confide to Judge Jones dismaying news from Madrid from the
Spanish police that very morning. The news "cast some doubt on the
identification". This information, he added, "was classified or
potentially classified".
The prosecutors then huddled with the
judge in his chambers. After 20 minutes, Judge Jones stormed back out
and announced that the prosecutors needed to tell the defense lawyers
what they had just told him. The prosecutor duly informed the courtroom
that the Spanish police had identified the fingerprint as belonging to
the right middle finger of Ouhnane Daoud, an Algerian national living in
Spain. Daoud was under arrest as a suspect in the bombing. Judge Jones
ordered Mayfield to be freed. The U.S. prosecutor said he should be
placed under electronic monitoring, a request which the judge turned
down.
Four days later, on May 24, the warrant for his detention was dismissed.
The
FBI sent two of their senor fingerprint analysts to Spain on a mission
to salvage the Bureau from humiliation. The two analysts did their best,
returning with the claim that the fingerprint sent to the FBI by the
Spanish police was of "no value for identification purposes", a claim
which the inspector general later shot down by pointing that only a few
weeks thereafter the FBI’s latent fingerprint unit concurred with the
Spanish national police lab’s determination that the print on the bag
matched the right middle finger of Ouhnane Daoud.
The FBI lab
fought an increasingly desperate rearguard battle, eventually claiming
that it had been the victim of an excessive reliance on technology. The
inspector general points out that the only investigator in the FBI’s lab
to emerge with any credit is in fact the IAFIS computer that had stated
clearly, "close, no match".
The inspector general writes the
bottom line on the "science" of fingerprint matching He gets the FBI’s
top examiner to admit that if Mayfield had "been like the Maytag repair
man" and not a Muslim convert married to an Egyptian, "the laboratory
might have revisited the identification with more skepticism."
And
Daoud’s fingerprint match? We don’t know, but if he was convicted on
the basis of fingerprints alone, we would say there is grounds for an
appeal.
