By James J. Mangraviti, Jr., Esq.
An expert witness who is feared and respected by the opposition is known as a dangerous expert.  Dangerous experts are extremely valuable to retaining counsel, are in high demand, and command premium fees.  A truly dangerous expert is one that is highly resistant to cross-examination and who is able to take advantage of the opportunity to turn the tables on opposing counsel.
An expert who is highly resistant to cross-examination is a so-called “bulletproof” expert and will:

• tell the truth and be consistent and non-evasive,
• prepare thoroughly,
• avoid conduct that could subject the expert to successful cross-examination,
• use proven expert cross-examination techniques,
• anticipate the likely areas of inquiry that he can expect to face,
• know how to defeat counsel’s tactics, and
• be able to artfully answer trick and difficult questions.

An expert who is able to take advantage of the opportunity to turn the tables on opposing counsel will use such opportunities to:

• employ powerful, memorable language that conforms to retaining counsel’s theory of the case,
• correct counsel’s subtle or blatant false premises and mischaracterizations, thus causing counsel to lose credibility with the jury,
• research opposing counsel and thus be better prepared for his tricks,
• focus on the key issue in the case,
• confidently but respectfully defend himself and his opinion, and
• let counsel look like the jerk, not him.
