BY ALL APPEARANCES, the sexual assault case against three members of the Duke University lacrosse team involves serious prosecutorial misjudgment, if not downright misconduct.
Michael B. Nifong, the Durham County, N.C., prosecutor, made public accusations long before the conclusion of the investigation and now forges ahead even as DNA, witness statements, medical reports and other evidence lead impartial observers to find the case ridiculously weak.
Sadly, such conduct is not uncommon. Prosecutors blatantly or subtly overstep professional bounds all too frequently. In a 2003 study, the Center for Public Integrity found that, since 1970, trial and appellate courts cited prosecutorial misconduct as a factor when dismissing charges, reversing convictions or reducing sentences in more than 2,000 cases. In thousands more, courts labeled prosecutorial behavior inappropriate but upheld convictions nevertheless.
The New York-based Innocence Project, whose DNA testing has led to the exoneration of 180 wrongly convicted people in the last 15 years, has studied these cases. It cites the following prosecutorial abuses as contributing to the punishment of the innocent: suppression of information favorable to the defense, knowing use of false testimony, improper closing arguments, coerced witnesses, false statements to the jury and fabrication of evidence.
Maybe such shenanigans will seem unsurprising -- just a case of lawyers being lawyers. As the joke goes, what's the difference between lawyers and liars? The pronunciation. (I can make the joke. I'm a lawyer.) But prosecutors are supposed to be different. They are public servants who are supposed to be committed to justice rather than the single-minded pursuit of victory. The Supreme Court has referred to their "twofold aim": to ensure that "guilt shall not escape or innocence suffer."
Why is the second half of that command often neglected? Why do some prosecutors seem indifferent to the risk that their behavior will result in punishment of the innocent? The answer to these questions involves a combination of at least three factors.
First, the asymmetry of the criminal justice system arguably places unrealistic demands on prosecutors. Defense attorneys may pursue acquittals without regard for truth and are subject to few ethical constraints. For example, defense attorneys generally are not bound to share evidence unfavorable to their client, but a prosecutor's failure to share exculpatory material is a serious no-no likely to result in a conviction being reversed. Prosecutors understandably aren't fond of unequal combat. With trials structured as zero-sum competitions featuring a clear winner and loser, they resist allowing their opponent overwhelming tactical advantage.
