I’d love to know the evidence, after such a fire you’re going to have to really struggle to find the cause, yes you might find the base of the fire and whatever set it off, but to try and nail that down to one person in the ship has got to be bloody hard, I would imagine several have an access to the area and I wonder what evidence is there to pinpoint one person, heck you’ve got the civilian construction crews plus the Navy personnel on the ship.
