Surveys have established that jurors rely heavily on forensic testimony in a high percentage of cases. In many cases, jurors report that forensic witnesses were very persuasive in the ultimate outcome of the case.
For the forensic witness to continue in this posture of pre-eminence in the legal process, it is essential for the witness's expert testimony to be able to withstand the challenges of rigorous cross-examination.
Effective cross-examination is often an objective technique to attack or impeach the testimony of a fraudulent or unethical forensic witness. Cross-examining attorneys can challenge forensic testimony based upon:
- Fraud.
- Unethical behavior.
- Incomplete or inadequate investigation.
- Lack of preparation.
- Inexperience.
