Expert witnesses get paid a lot of money for their testimony, Alyce, Samuels chose to testify and chose to support Jodi's defense based on their own "expert" opinions. They were both careless in their assessments and their testimony and both were shown they were biased.. IMO an expert witness has to be very very objective, not show they are favoring a particular outcome, they lost credibility by the time Juan was done with them, as they should have. They clearly would have said anything to support Jodi and, Thanks to Juan, it was very transparent. They damaged their own reputations. I think that is what this is all about. I would not want to offer up to be an expert witness and face Juan after seeing how these two did.
