I believe I've seen enough to draw a conclusion.
I'm willing to keep an open mind if more facts become available...but right now, it looks like the "journalist" should have died and not the Italian agent, and that seems to be the only "accident".
I agree I've seen enough to conclude the journalist's story is highly suspect, to put it conservatively. I'm looking forward to seeing what a more detailed disclosure of the crime scene details reveals. There are some questions I'd love to see answered, such as some of the ones you've raised.
