Yeah, the prosecutors better keep their minds tuned to the "down to earth" side that most juries have.
I trust Brocchini's judgment that there was probably nothing in the guy's account of this "body disposal" discussion.
BUT, the jury does not always agree with the lawyers and witnesses as to what is significant, and THEY have the last word on what is significant! I can just see them coming back, after an adverse verdict, and saying, "We wish we could've gotten a chance to judge that college friend's tip for ourselves."
It's exactly what I was thinking, many cases have been decided based on the testimony of someone's word against another and who the jury believes. Denying the jurors in this instance of hearing the college friend in person could ultimately backfire on the prosecution even though many at this point think it helped them.
