The Passions and the Interests in Forensic Science

by Roger Koppl A front-page article  in yesterday’s Washington Post underlines the importance of establishing a substantive defense right to expertise in the US. The article says, “Justice Department officials have known for years that flawed forensic work might have led to the convictions of potentially innocent people, but prosecutors failed to notify defendants or … Continue reading The Passions and the Interests in Forensic Science

Epistemic monopoly is still a bad thing

by Roger Koppl McClatchy-Tribune Information Services has been distributing my op ed with Dan Krane on "Science rules the FBI should obey."  We discuss an example of epistemic monopoly in action, namely, the FBI's failure so far to release anonymized data from its vast NDIS (National DNA Index System) data set.  The NDIS data set contains … Continue reading Epistemic monopoly is still a bad thing

The New Interventionist Economics

by Roger Koppl Two recent posts on this blog (here and here) raise the issue of animal spirits and where macro is headed.  I’ve recently completed a draft manuscript saying we are headed for “BRACE” economics.  I say the “New Interventionist Economics” will be characterized by five features: Bubbles Radical Uncertainty Animal Spirits Complexity Dynamics … Continue reading The New Interventionist Economics

Rent Control and Torture

by Roger Koppl Dick Cheney has intimated that water boarding yielded important, actionable intelligence.  The evidence points the other way, however.  Some evidence suggests that there may have been an ulterior motive for at least some “harsh interrogations,” namely, to link Iraq and al Qaeda.  We need more analysis of Bush-era torture from an economic … Continue reading Rent Control and Torture

Now it’s official: forensic science is a mess

by Roger Koppl The NAS released a much-anticipated report on forensic science last month.  The report said, “With the exception of nuclear DNA analysis, however, no forensic method has been rigorously shown to have the capacity to consistently, and with a high degree of certainty, demonstrate a connection between evidence and a specific individual or … Continue reading Now it’s official: forensic science is a mess

A Gem in the Folded Palm of Forensic Science

by Roger Koppl I’ve been railing against epistemic monopolies for a while now, particularly in forensic science.  This project complements Peart and Levy’s work on experts.  (See their symposium the 2008 Eastern Economics Journal, vol. 38 starting page 103.)  I keep insisting that we need redundancy to reduce error rates.  Economists, forensic scientists, and philosophers … Continue reading A Gem in the Folded Palm of Forensic Science

Flaming torches and pitchforks

by Roger Koppl Forensic scientist Brian Gestring laments “The Dawn of the ‘Forensic Science Provocateur’” in the latest CAC News.  That’s the newsletter of the California Association of Criminalists.  He objects to the “peripheral waves of lawyers and business professors that have . . . found a new calling, that of Forensic Science Provocateur.”  But … Continue reading Flaming torches and pitchforks

If redundancy is good enough for the rich and famous . . .

by Roger Koppl According to Associated Press, “Bahamas using 2 experts for Travolta son autopsy.” (HT Ed Lopez.)  Actor John Travolta’s son Jett died tragically on Friday, January 2nd, after hitting his head in a fall.  (It seems he had an illness that left him subject to seizures.)  The E! News story says, “A government … Continue reading If redundancy is good enough for the rich and famous . . .

Epistemic monopoly may let the bad guys get away

by Roger Koppl The Chicago Tribune gives us another example of the trouble with epistemic monopolies.  They uncovered a case in which the police in the Chicago area city of Harvey, Illinois ignored a DNA match in a rape case.  In two other rape cases they did not submit the rape kit for analysis.  Madison … Continue reading Epistemic monopoly may let the bad guys get away

Who needs that new-fangled DNA anyway?

by Roger Koppl It seems some police and prosecutors do not view DNA evidence as friendly to their cause.  I’ve come across two cases in which the police won’t use available DNA evidence.  Earlier I blogged about Baltimore, where the police were ignoring DNA evidence.  Now the Chicago Tribune reports, that in Lake County, Illinois, … Continue reading Who needs that new-fangled DNA anyway?

The Technical Obsolescence of Forensic Fraud

by Roger Koppl I gave a webcast yesterday on “How to Improve Forensic Science.”  Online questioners challenged me on a point that I now recognize to be underappreciated: The “ACE+V methodology” of fingerprint examination lets you shop your verifications.  Let me explain. Fingerprint examinations are performed using the “ACE+V methodology.”  The acronym stands for Analysis, … Continue reading The Technical Obsolescence of Forensic Fraud

Truth-challenged police forensics in Baltimore

by Roger Koppl Most people think DNA evidence is bulletproof.  Molecular biologist and forensic scientist Dan Krane has very nice presentation on some of the problems that can arise in this area.  When the biological sample is mixed, degraded, or small, the evidence can be ambiguous, which allows subjective judgment to enter.  Recent events in … Continue reading Truth-challenged police forensics in Baltimore
