Introduction to Cross-Examination

Few prosecutors have the scientific skills to challenge a defense DNA expert on the science of DNA. However, cross-examination of the defense expert involves the same skills that prosecutors use daily in their examination of any type of defense expert. Successful cross-examination consists of:

• Careful preparation with the state's DNA analyst;
• Drawing concessions from the defense DNA expert witness; and
• Attacking the defense DNA expert witness on the areas of expertise and bias.

In this topic you will learn about conducting successful cross-examinations.
