What is a defense “expert”? To the inexperienced or unenlightened lawyer, the thought of cross-examining the other side’s “expert” may conjure up fear and doubt. In reality, experts are of varying professional quality and temperament: they can be very good, or they can be mediocre, maniacs, shoddy, BS artists, money-hungry vultures, myopic, arrogant, angry, condescending, unprepared, and the list goes on and on and on.
The point is that cross-examining experts is really not any different than with a lay witness. In fact, I find it easier.
