There are so many facts that are ignored. The ballistics expert for the defence carried out a series of experiments showing that the glass deposition in Filomena's room could only have arisen from a stone thrown from outside. But the judges appear to prefer their own opinion (or I suppose that of the prosecution) that the stone was too big to be thrown through the window (although the experiments were carried out by throwing a similar sized rock), and that the outside shutters which were part closed when photographed must have been in the same position unless the defence prove otherwise, and if the shutters are part closed the stone could not be thrown through the window. Therefore the glass deposition must be a consequence of staging by the defendants. The only person with an interest in staging is ….. Knox.
So one could argue the whole case rests on the position of the outer shutter, and whether that might have moved. FWIW if I was a burglar and had broken in through that window I would have pulled the outer shutter closed after me to conceal the broken window from passers by.
Here is the embedded glass shard. The blue arrow points to the location, unfortunately to load the picture I had to reduce the size, and detail.

The unresolved question is the velocity required. The maximum is 28 mph as the release velocity for a record female shot put, same weight as the rock. Rudy Raffaele or Amanda could not achieve this.
There may be a spring effect as the glass breaks driving this shard somewhat remote from the impact crater, at a higher speed than the rock impact. What is interesting is the glass shard embedding while the shutter is being thrust open. I have long held that all the ballistics required to achieve this high velocity bullet like embedment could never be countenanced while attempting to clandestinely cover for a homicide. It is notable that no
pgp, including The Machine Harryrag were aware of this picture even a month ago. They refuse to engage, yet despite mumbling photoshop know that this never happened. The photographs were taken the day the body was discovered, and can be forensically employed to finally disprove the staging of a break in.
