In recent years a large number of individuals in the U.S. have been exonerated
after spending years in prison for crimes they did not commit. Some spent
decades in prison and some were on death row. In a number of highly publicized
murder and rape cases DNA evidence was critical in showing the individuals
convicted were in fact innocent.
Last year there were 125 exonerations nationwide. Of these, Harris County
accounted for about a fourth, with 33. But it was not DNA evidence that
proved their innocence, and the cases did not involve violent crimes.
Instead, the Harris County exonerations came about after a thorough review
by the D.A.'s office of drug convictions in which questions had arisen
about the accuracy of lab test results.
The 33 individuals exonerated in Harris County had been convicted on relatively
minor charges of drug
possession. The individuals had pleaded guilty before lab results came back. When
the D.A.'s office later reviewed the lab results, it found insufficient
evidence of an illegal substance.
Some people may wonder why a person would plead guilty to a crime they
know they didn't commit. The answer most likely lies in the procedures
governing pretrial release. The individuals who were exonerated probably
couldn't afford bail and could not get a recognizance bond. As a result,
they would have to remain in jail until their trial, separated from their
loved ones and risking the loss of jobs. Drug lab results can take months
to come back, and many individuals likely pleaded guilty in order to get
The number of innocent people exonerated shows the importance of an aggressive
defense in drug cases. An experienced defense lawyer can fight for pretrial
release and scrutinize lab results for mistakes and inconsistencies before trial.
