Prosecutor misconduct threatens fair trials201 misconduct cases reviewed
By Brad Heath and Kevin McCoy | USA TODAY • and Brian Haas | THE TENNESSEAN • September 23, 2010 Assistant U.S. Attorney Delk Kennedy Jr. acknowledges he lost his temper during closing arguments at a 1998 bank robbery case in Nashville when the defense raised questions about a key eyewitness. "I jumped up and said, 'It's a lie, it's a lie, it's a lie,' " Kennedy said Wednesday. "The closing argument in any case, that's when emotions run high." But the outburst nearly cost the federal government a conviction and led to a federal appeals court rebuking Kennedy for conduct that "misrepresented critical evidence at the close of trial" and probably influenced jurors.
In a West Tennessee federal court, a prosecutor withheld evidence in a 1992 mail fraud case that led to a conviction being overturned. Another prosecutor there tried to convince a jury that by putting someone on the stand, he was "vouching" for a witness' honesty. The conviction was upheld, but an appeals court called the prosecutor's actions "improper and even inexcusable."
Federal prosecutors are supposed to seek justice, not merely score convictions. But a USA TODAY investigation found that prosecutors have repeatedly violated that duty in courts across the country. Judges have warned for decades that misconduct by prosecutors threatens the Constitution's promise of a fair trial. Congress in 1997 enacted a law to end the abuses. Yet USA TODAY documented 201 criminal cases in the years that followed in which judges determined that U.S. Justice Department prosecutors themselves violated laws or ethics rules.
In case after case, judges blasted prosecutors for "flagrant" or "outrageous" misconduct. They caught some prosecutors hiding evidence, found others lying to judges and juries, and said still others had broken plea bargains.
