THEY DID! The bug expert the defense called today was certified.
I am not real sure what determines being certified. First I would think they would have to have a certain degree in entomology.
Dusek did not challenge the credentials of either entomolist as expert witnesses, so their testimony must be accepted as that of a knowledgable person in that field and if Dusek cannot find another expert or two to contradict the two that have testified, the jury must accept as true the evidence presented by the two experts so far. That being the case, the jury would have no choice but to acquit DW.
