To those who have been exonerated or convicted because of DNA evidence, the realization that DNA evidence isn't infallible must be mind-blowing. How does it feel to sit in prison wondering if a typo or bad handwriting were part of the reason for your conviction?
The discoveries, submitted by the New York City medical examiner’s office to a state oversight panel, show that the capacity for human error is ever-present, even when it comes to the analysis of DNA evidence, which can take on an aura of infallibility in court, defense lawyers and scientists said.In a world where the majority of defendants accept a plea agreement, the prosecution doesn't need to prove anything to a jury. When the prosecutor can pin a defendant between a mandatory minimum sentence and a plea agreement--and going to trial can add years to one's sentence--the prosecution can be confident that anything they say about DNA evidence will not be challenged.
A prosecutor's best tool is supposed to be evidence that the defendant committed this particular crime. Instead, his best tool is the mandatory minimum sentence.
This is not a reliable path to justice.
