Thanks for this, and thanks to anglolawyer and abytesla also. I won't clog up the thread with multiple replies.
Ok, feel a bit dumb for not having gleaned this - my discussion is with people who seem to think that its either from the outside or inside and this is what I had thought the prosecution had suggested as well. I may have been distracted by John Douglas in the Forgotten Killer who says in the staged section of his chapter
"photos reveal that prior to breaking the window, the rock first struck the inside edge of the exterior shutter, indicating it was thrown from outside......glass fracture examination of the window would prove this." -
Anyway thanks for the replies. On a more general note, is there any source (meaning court) document that shows the lack of cooperation from the prosecution and/or refusals by the court of defence applications to test evidence? I'm having trouble finding English translations of the procedural stuff. Arguing that the process was weighted against the defendants is so much easier with source docs.
I won't keep doing this sorry
