However the evidence of the bullets came about, come about it did.
The manner in how it came about is also quite telling. Everyone, including his father, could see just how damning this evidence was/is.
A more compelling case for someone's guilt, would be hard to find. I notice that his supporters play heavily on the fact that he served, for a number of years, in the army. I fail to see how this is in any way relevant.
Was there ever any link established between Ross and the waiter, or was he a completely random target?
