Alfred Swinton; Connecticut; Flawed bitemark science: John Stossel's timely reminder in 'Reason' that junk science sends innocent people to jail - and that reform is long overdue..."The TV show Cold Case Files covered the trial of Alfred Swinton. He was convicted of murder because a bite-mark expert said his teeth matched a bite on the victim. "A perfect match!" said Dr. Gus Karazulas, the "forensic odontologist" whose testimony clinched the conviction. Karazulas sounded impartial and objective. "A forensic scientist is not on the side of the prosecutor or defense," he said on Cold Case Files. "We look at the evidence." But Swinton was innocent. Lawyer Chris Fabricant helped get him released from jail by doing a DNA test, a much more reliable, less subjective form of science. Fabricant scoffs at bite-mark testimony: "The doctor was just wrong. It's an unreliable technique."
PASSAGE OF THE DAY: "Bite marks are just one dubious method police and
prosecutors use. FBI researchers claim fingerprints are right more than
99 percent of
the time. But that still leaves plenty of wrongful convictions. After
terrorists killed 193 people in Madrid, the FBI matched a
fingerprint on a terrorist's bag to a man in Oregon named Brandon
Mayfield. They arrested him. But Mayfield was innocent. Weeks later,
Spanish investigators compared the prints more carefully and found the
real terrorist. Other techniques are even less accurate: carpet-fiber
evidence, gun tracing, use of psychics, hair matching. "A dog hair was
associated wrongfully with a human hair," says
Fabricant. "Since the turn of this century, there have been 75 wrongful
convictions (based on hair matches)."
QUOTE OF THE DAY: "Why do judges and lawyers accept such dubious evidence? "We all went to law school because we don't know science, we don't
know math," he replied. "If somebody comes in in a white lab coat, and
says, 'I've been accredited by the American Board of Forensic
Odontology,' that's good enough for government work." That shouldn't be. Too much is at stake.
Jurors tend to believe people who call themselves "scientists." Judges
should be more skeptical. They should ban junk science from
courtrooms."
POST: "Junk Science Sends Innocent People to Jail," by John Stossel, published by Reason on May 23, 2018. Reason informs us that the former host of Fox Business' Stossel and ABC's 20/20 - who joined Reason in 1917 - has won 19 Emmys and authored several best-sellers."
GIST: "On TV crime shows like CSI, NCIS, and Law & Order, science gets the bad guys. In real life, "science" often ensnares the innocent. Former NYPD Detective Harry Houck gets annoyed when TV shows make forensic science look infallible. "You watch a detective get down and look at a body (and say), 'He's
been dead for three hours now... (H)e ate dinner four hours ago,'"
scoffs Houck. "I can't do that." On TV, experts identify killers by their bite marks. In real life, experts claimt hey can do that. The TV show Cold Case Files
covered the trial of Alfred
Swinton. He was convicted of murder because a bite-mark expert said his
teeth matched a bite on the victim. "A perfect match! said Dr. Gus
Karazulas, the "forensic odontologist" whose testimony clinched the
conviction. Karazulas sounded impartial and objective. "A forensic
scientist is not on the side of the prosecutor or defense," he said on Cold Case Files.
"We look at the evidence." But Swinton was innocent. Lawyer Chris
Fabricant helped get him
released from jail by doing a DNA test, a much more reliable, less
subjective form of science. Fabricant scoffs at bite-mark testimony:
"The doctor was just wrong. It's an unreliable technique." The more room
there is for an expert witness's unique interpretation
of the data, the more that can go wrong, says Fabricant. "Bite mark is
similar to you and I looking at a cloud. I say to you, 'John, doesn't
that cloud look like a rabbit?' And you say, 'Yeah, Chris, I think that
does look like a rabbit.'" That kind of junk science puts innocent
people in jail. I told Fabricant that I assumed most people in jail are
guilty. Also,
many people say crime is down because aggressive law enforcement has
locked so many people up. "If you think that maybe even 1 percent of
convicted defendants may
be innocent," replied Fabricant, "we have 2.6 million people in prison
today, (so) we are talking about tens of thousands of (innocent)
people!" Fabricant works with the Innocence Project, a group that works
to get
innocent people freed from prison. Through DNA evidence, the project's
lawyers have helped free 191 people. That confident bite-mark expert who
got Swinton convicted now admits
he was wrong. "Bite mark evidence is junk science," he told us via
email. He resigned from the American Academy of Forensic Sciences. But
police still trust bite marks. "Let's say one tooth is missing in the
front" of a bite mark,
explains Houck. "You've got to go, well, our suspect's got one tooth
missing in the front. That's pretty good!" Houck says he'd demand other
evidence. But not all cops do—especially when scientific "experts" say
someone's guilty. Bite marks are just one dubious method police and
prosecutors use. FBI researchers claim fingerprints are right more than 99 percent of
the time. But that still leaves plenty of wrongful convictions. After terrorists killed 193 people in Madrid, the FBI matched a
fingerprint on a terrorist's bag to a man in Oregon named Brandon
Mayfield. They arrested him. But Mayfield was innocent. Weeks later,
Spanish investigators compared the prints more carefully and found the
real terrorist. Other techniques are even less accurate: carpet-fiber evidence, gun tracing, use of psychics, hair matching. "A dog hair was associated wrongfully with a human hair," says
