I think there is a line drawn somewhere between suggesting what could have happened and stating what actually happened.
I'm not sure why it is bothering you so much what a few eejits on this thread are idly supposing.
We all know we're unlikely to be correct. It is bothering us. I'd love it if someone came along and disproved all the suggestions being made. But nobody has.
It's horrible and probably pointless but when something is so hard to escape due to inordinate amounts of press coverage, it can and does aunt a lot of people mentally, and can be very hard to stop thinking about.
Which of course says more about the vulnerability of some posters, and less about the people truly involved.
But MN is good for getting things down, rather than having them going round in ones head all day. I apologise if anything I've said has offended you personally.
