THE trial of William Kennedy Smith gave us a televised glimpse of how American justice is increasingly influenced by the participation of paid expert witnesses in criminal and civil trials.

The defense called an architect to show that if the woman had screamed as she claimed, she would have been heard by people inside the house.
The use of an expert's opinion to impair or bolster the credibility of a witness is an indispensable tactic of the modern trial lawyer. The need for these experts has inspired a national marketplace for the buying and selling of expert opinions.
Many of these expert witnesses-for-hire exhibit a chameleon-like ability to adapt their opinions to satisfy the needs of their employers. The misuse of paid expert witnesses to create or dispel reasonable doubt in a criminal case or to fix liability and damages in a civil case has become a scandal in American courts.

Organizations dedicated to finding and delivering an expert to render sympathetic opinions pitch their experts to lawyers with glossy brochures, direct mail advertisements, and toll-free numbers.
Finding the right expert witness can mean the difference between triumph and failure in the all-or-nothing world of jury verdicts. A psychiatrist is used to hang a jury by creating reasonable doubt about the defendant's state of mind; an expert in accident reconstruction disputes an eye-witness account over the cause of a traffic fatality.
