There is nothing wrong of course with being undecided and wanting to see more "hard evidence" before deciding anything.
However, if other people do see something, anything as "hard evidence" and make up their mind, then they are accused of believing rumors, making personal attacks, fueling tabloid speculation, etc, etc.
That's not fair, I think.
It's not fair to decide what is and is not evidence and repeatedly tell people that they should not discuss anything here or at all. That is just opinion, on either side.
And yes, if on every single point brought up here, on every single discrepancy of version of events, there isn't even the slightest concession towards "that could be right, it's possible--" as in with Jane Tanner's version--then the logical conclusion is that someone's mind has been made up on the issue of the McCanns' involvement.
It's not logical to assume that merely because Jane Tanner says something, it's the truth. To examine her version and question it is logical. It doesn't mean she isn't telling the truth to do so.
It's not cruel or heartless to point out that her version of the story has changed, and this has not been refuted publicly either by Jane herself or by legal representation on her behalf.
It may be distasteful to you to see people debating these issues but miscarriages of justice are carried out by the courts, not by a free people exercising what is for us, a constitutionally protected right to freedom of speech.
