Wow... there's a real positive thought to add to the discussion. I'm pretty sure this was supposed to be a motivational/inspirational thread. If it's not your cup of tea, just skip it next time.
Sure, it's tragic, and they knew the risk, but the rewards weren't expected to be discovery but were seen as celebrity and we have way too much of that as motive now for foolhardy behavior.
So, if it happens again, do we reuse the same hankies or do we ask the really important questions?
