We don't have enough information, was the body found at depth, stiff, and blue, then bc inflated so it surfaced? Was death so obvious that bringing him on board would destroy evidence of foul play? This is unknown and making assumptions is a bit premature. As I said before, who is the expert on local protocol? It is protocol for floating dead divers to be left alone until officials arrive? We don't have enough information to be making bold statements one way or the other.
On the flip side, was the body in the water alive and only watching something below them? So many possibilities and not enough information to determine definitively what actually occured. I would expect that the boat captains did exactly as the officials demanded.
