Texas bill allows defendants to challenge their convictions based on junk science

Per the Innocence Project's blog today, "A bill passed by the Texas Senate this week would provide an avenue for prisoners to challenge convictions based on discredited forensic science." They reference a story in the Marshall News Messenger that begins,

Criminals who were sent to prison — or sentenced to death — based on discredited scientific evidence would be given a new way to challenge their convictions under a bill passed this morning by the Texas Senate.

In recent years, an increasing number of arson and gunshot convictions in Texas have triggered alarm as new technology proved earlier evidence wrong, and convictions were cast into doubt — including at least one case in which the prisoner was executed.

The measure by state Sen. John Whitmire, D-Houston, would allow discredited scientific evidence that figured in a criminal conviction to be considered by an appeals court in order to establish the innocence of a defendant...

Advancements in forensic testing — DNA, ballistics and arson — have led to new evidence being uncovered in several cases in Texas. Whitmire said that led him to file the bill, which clarifies how discredited scientific evidence can be used in court appeals.
In December 2008, we worked to overturn Jimmy Ates' conviction, based largely on fraudulent FBI bullet lead analysis. Since then, the National Academy of Sciences has issued a scathing report, decrying the sorry state of forensic science labs around the country.

We know well how junk science can contribute to a wrongful conviction – indeed, the Innocence Project in New York says that junk science contributed to over half of the nation's first 225 DNA exonerations. We applaud steps like these being taken in Texas, and hope that a new incredulity toward and accountability regarding forensic science will spread to other states and jurisdictions.
