The nature and role of expert forensic testimony

There will probably always be tension between trial advocates and expert witnesses of all disciplines. The reason is that each of them speaks a different language, and each of them is regarded as an 'expert' in what he or she does. It is important for the 'expert' criminologist to appreciate that professional trial advocates do not take kindly to other so-called experts trespassing on their turf and parading another expertise before the jury or trial judge. Call it professional arrogance, but in a courtroom, trial advocates tend to regard themselves as the only experts who should be seen and heard.
