Expert Witness Preparation
It is essential that attorneys and experts discuss the case facts and testimony prior to trial so that the extent of technical detail is predetermined and the attorney made aware of any potential weaknesses in the result and/or the technology used.
If the attorney is unfamiliar with DNA, a primer on DNA testing should be reviewed prior to trial.
If the witness is new to testifying, a primer on rules of evidence, direct and cross examination, and courtroom etiquette should be reviewed.
