Systemic Injustice

We know the factors of failed justice.  Often, they form a syndrome.  No single correction or remedy will address them all.  The cures cannot be legislated.  Like all crime, ultimately it comes down to the individual who makes the choice.  Scandals are rooted in bad society, when injustice is rewarded because of willful corruption or careless disregard for consequences.  That may be easier to fix. 


Tucker Carrington, the director of the Mississippi Innocence Project, says he and his colleague Will McIntosh decided to pursue Mabry's killer themselves after they attempted to bring the case to the attention of the prosecutor in Humphreys County, and then to Hood's office, and received no response from either.

“When you take on a case and it reveals a glaring injustice like this -- something that could easily be taken care of if someone would just give it some attention -- you can't just turn a blind eye to that," Carrington says. "In the end, I guess we saw this through because no one else would.”

“In fact, the way forensics are handled in the courtroom has become a persistent problem across the country, not just in Mississippi. Forensic scandals have been erupting at crime labs nationwide over the last decade. Most recently, there was a scandal at the state drug lab in Massachusetts that could affect thousands of convictions; another drug lab scandal in Nassau County, N.Y., that could also hit thousands of cases; and misconduct at the state crime labs in Connecticut and North Carolina that have led to reviews of hundreds of cases, including murder convictions. Currently, there's an ongoing controversy involving the FBI's crime lab, in which analysts were found to have vastly overstated the significance of hair and fiber analysis while testifying in court. That too has spurred a review of thousands of cases going back more than a decade. The FBI lab had been considered one of the most elite crime labs in the world.”

A decade later, more-advanced DNA testing determined that there was semen from two men inside of Jackson, and neither of them was Kennedy Brewer. The state Supreme Court ordered a new trial. Despite the test results, Allgood planned to prosecute Brewer again. When The New York Times asked him why he hadn’t bothered checking the crime scene DNA against the state’s DNA database, Allgood replied that the state doesn’t have such a database. This came as a surprise to the man who had been running it.

I've written an actual case study that has examples of most of the procedural errors that can be made by law enforcement officials.  It began with the murder of a girl, the arrest and trial of three men two of whom were convicted and sentenced to death.  Later the Illinois Supreme Court overturned the convictions and the prosecution tried the individually two despite the admission of guilt by a third party. During two new trials, convictions, and two subsequent Illinois Supreme Court appeals, the prosecutors refused to admit error even when the third man’s DNA proved his guilt. (Meanwhile he committed two other murders.)  After a preliminary hearing where one policeman’s previous testimony proved erroneous, a new judge ordered the release of the accused.
Unlike other prosecutions full of procedural errors, this one resulted in the investigation, indictment, and trial of three policemen and two prosecutors who were found not guilty. Nevertheless, a new prosecutor ordered an examination of the facts and subsequently indicted and tried the real killer who was found guilty and sentenced to death.  He has not been executed as Illinois has a moratorium on the death penalty.
Meantime the convicted men filed a civil case in federal for wrongful imprisonment, and it was settled by the county where the criminal trials took place for three million dollars.

A Forensics Bibliography

Westwood High School in the Round Rock Independent School District outside Austin runs a science class in forensics.  On Tuesday, May 8, 2012, I spoke to four forensics classes joined by two psychology classes on the topic of forensic psychology.  On the one hand, we all do forensic psychology every day.  Beyond that, most of what passes for profiling - especially via the mass mediated hyper reality of crime presented via television and the Internet - is junk science in the courtroom. 

This is the bibliography for those presentations.

His theory of “differential association” led to other “differential” theories. This textbook begins with causes and ends with parole.

Why Evidence is Not Enough

Generally, people rated authors as experts when the views coincided with their own. Kahan and his team created three authors and their books. All three had the same high level of academic standing. (Doctorates from major schools.) In every case, two different, opposing views were written for each author and randomly shown to subjects. The topics were gun control, nuclear power plants, and global warming.

Originally published by the Yale Law School as "Research Paper #205: Cultural Cognition of Scientific Consensus by Dan M. Kahan, Hank Jenkins-Smith and Donald Braman." The paper can be downloaded from the site of our comrades at Mother Jones who offer it here.

This is really just another arithmetic validation of what we know as the "confirmation bias" and the "attribution fallacy." Richard Feynman warned young scientists about the need for ruthless honesty in his famous speech on "Cargo Cult Science." (Available from the CalTech Engineering and Science Library here.)

In short, we tend to agree with and thereby validate experts who agree with us. When presented with facts opposed to our commitments, we denigrate the status of the provider. This ties in with another theme: The Big Sort by Bill Bishop. Over the past generation, Americans have come to socialize only with those who agree with them politically. In the 1960 Presidential election, Kennedy won over Nixon by about 1 vote per precinct, and largely, it was just that: a nation mostly divided narrowly near the middle. Now, precincts tend to be overwhelmingly Republican or Democrat.

It is not just gerrymandering (though there is that), but the fact that people choose to live among those whose political values already mirror their own. The research data show that this correlation is strongest among those with more education. The guys on the bowling team might disagree and still hang out; their bosses on the golf links do not.

Today, perhaps more than a third of working American adults hold bachelor degrees, with the master's being the new bachelor's. University education apparently failed to achieve the lofty goals of Karl Popper and Mark Van Doren two generations ago for a society open to ideas, whose participants benefited from a liberal education embracing literature, mathematics, science, and fine arts.

The blog OrgTheory is written by sociologists of economics, Brayden King, Fabio Rojas, and others. On April 11, 2011, Brayden King posted "When Evidence Isn't Convincing." It summarized research by Daniel Kahan and his colleagues.  Reading that and following the links to the original paper, I posted an earlier version of this blog article to the Objectivist site, Rebirth of Reason.
