I don't fault JB for using this "expert" though. He came with the Expert Economy Pack.I'm beginning to see that this witness is like Dr. Fairgrieve. Reads alot, but really not an expert of anything.
IMO this defense wit is stuttering more when responding to JA... not in a "how can I rephrase this" way but more in a "uh, ah, oh dear these are real questions" way...
