Was the Questioning from Logiudice Real?

[Jan]

About half way through the book I began to wonder if this was Andy's way of sorting through things. After Jacob's trial, Andy tells us that Logiudice no longer works for the DA - that he has become a defense lawyer. That seems to support that it wasn't actually testimony before a Grand Jury. It seems a natural way for Andy to work things out - even though he is still in denial about many things. What do you think?
