1. I always felt that involving the 5 inmates was stupid, stupid, stupid, because it negated Hendry's marvelously simple genius of the Guede-Lone-Wolf scenario, and opened the door to "more than one killer"
2. Why do you believe that lying, raping, Meredith-violating Guede????
The Motivation Report rejects the lone-wolf theory and the break-in so emphatically, I'm sure defense attorneys felt they had to put on witnesses who claimed to have heard RG put himself at the scene with anyone but AK and RS.
How could they risk not doing so?
As for Hendry, Umbrian courts seem to have an aversion to non-Italian expert testimony, so I'm sure the defense had no hope of getting Hendry into evidence.
