You will need to ask someone trained in the medical field. It would be interesting to hear what Vanezis opinion would be on this. However I don't think he will suddenly go "Oh My God Jeremy is Innocent" 
Why? We can all clearly see that blood is not 'free flowing', it is dry and cracked.
I'm happy to step back and bow to expert opinion on certain issues, but this isn't one of them.
In the same way, I don't need an expert to tell me if it is raining, I have the ability and knowledge (expertise perhaps) to look out of the window or stand in the garden and conclude wHether it is actually raining or not.
