That's absolutely your prerogative and I have no firm opinion either way, but I've asked several times in the last few hours for what was the clinching piece or pieces of evidence in this case and so far no one has given me anything that resembles evidence "beyond all reasonable doubt".
you're right, there wasnt one smoking gun in this case, but does there have to be? thats not how a multithreaded circumstantial case works.
the dury were presented hundreds of pieces of linked evidence during 42 day trial, pointing to the guilt of luke.
it'd exceptionally hard to distill the case against him down to a 2 part documentary thats easily digestible by casual observer
it boiled down to
- witness statements supporting sighting of him at top of path just before time or murder
- guilty knowledge of location of body and garments / accessories on body not visible post-death
- alibi found to be fabricated and destroyed on cross examination of brother
- missing knife / jacket
- hundreds of other supporting items of evidence which dont contradict all this
