Not reliable to you. We will see what the judges say. Same for the shop owner. RG is the new guy. He wasn't part of the first trial.
Rafaelle is the murderer so luminol hits at his house don't seem so strange to me. I guess they got lucky that MK's DNA wasn't found there. Oh wait, it was found.
It might be an interesting defense tactic to show that in regular households you can also find full bare luminol footprints, but for some reason the defense didn't do that. I wonder why?
This is insanity.
MK's DNA was NOT found at RS' house. That is now clear.
The luminol hits at RS' apartment were not the blood of MK, RS or AK. If they were, we would all have heard about it by now. They most likely weren't blood at all. Why is it so hard to understand that luminol reacts to lots of things (including bleach), not just blood?
The properties and limitations of luminol are well known. There was no reason for the defense to "prove them."
