Well do you agree that the room's occupant testified that there had been valuable items in plain view, none of which were taken?

I think he was looking for money. It was the 1st of the month and rent was due. Meredith had dated casually a guy downstairs and Rudy had hung out there. Also, I think it is likely he didn't expect to find anyone home and was interrupted when Meredith came home early, for an early night. I don't think he was planning to take objects, though might have if uninterrupted.

Also, Meredith's $300 was missing, and somehow he had the money to ride a train the next day to Germany.

I don't understand what point you are trying to make. There is a difference between saying that evidence can be explained away and saying that the evidence does not exist.

To have evidence of a break-in is different than having evidence of a staged break-in. Since there is evidence of a break-in, but not any that would say it was staged, there is evidence of an invented idea of a staged break-in. I'm not saying that a lack of evidence of something being staged means it wasn't. But going the rules in the post, there is nothing that would indicate it was staged from the evidence itself. That part is fallacious. It exists in the mind of Mignini, not in the evidence.

Does that clarify what I mean?

I'm sayinig he made up the staged part, since the evidence for a staging (rather than a break-in) did not exist in the crime scene. He imposed his ideas on the reality before him. He looked for things to support his idea, and those things were shown to be false or unrelated logically to Amanda.

Not really. For example, the ransacking of a room but the failure to take valuable items in plain view is evidence of a staging. Yes, there are other explanations for this evidence but that does not mean it's not evidence of a staging.

In terms of the rules of the post, it takes a leap to get to the idea of a staging. One has to infer it. Amanda's DNA is not on the glass or the objects, anyway, even in the unlikely event that there was a staging.

"In terms of the rules of the post, it takes a leap to get to the idea of a staging. One has to infer it."

Sorry, but I have no idea what this means. Interpreting evidence is always a matter of inference.

"Interpreting evidence is always a matter of inference."

Without physical evidence of something, how do you, except by imagination, come up with an explanation? Logic of the situation, yes. But this forms a tautology in this case. She broke the window and staged a break-in (though there is no physical evidence that suggests this) because... why? Because... someone wants it to look like she did the crime. My point was that komponisto showed how you have to have a reason in the situation itself to suggest it. This theory of the staged break-in is being used as a reason to suspect Amanda. The reason to suspect Amanda of a staged break-in is that more evidence is needed to implicate her in the crime. To say that "if Amanda staged a break-in, it would implicate her" may be true, but it would also be true of anyone. It could equally be true of the other two roommates, for example. The only thing that made Amanda stand out in this regard is that she was there first and that someone read into her behavior as significant.

This is how it seems to me.

"The reason to suspect Amanda of a staged break-in is that more evidence is needed to implicate her in the crime."

That's one reason. A better reason to suspect Amanda of a staged break-in is to note that there is in fact evidence of a staged break-in and to observe that (1) it's mainly somebody who was closely associated with the victim who would have had a motive to do such a thing; and (2) Knox had a good opportunity to do so.

"only thing that made Amanda stand out in this regard "

stand out compared to whom?

Sorry, but I have no idea what this means.

I find this hard to believe, particularly after the multiple explanations given to you. Even if these multiple explanations that leave open technicalities for exploitation by a reader who does not desire comprehension. I get the impression that you are being disingenuous. If not, please reread the grandparent again assuming the sentence "One has to infer it." was removed.

"I find this hard to believe, particularly after the multiple explanations given to you."

There's no way to prove it. But let's do this:

Please give me a couple of examples of evidence and (possible) conclusions which "require a leap" as well as a couple of examples of evidence and (possible) conclusions which do NOT "require a leap."

That should make things clearer.

  1. The house has been reduced to a pile of charred debris -> There was a fire.
  2. The house has been reduced to a pile of charred debris -> There was arson.

Anna would obviously call 2) a leap but not 1). I am aware that a similar process of inference is involved, differing only by degree and yet I am still able to grasp what Anna is trying to say. That Anna has explained what she is trying to say multiple times helps, as does my IQ. Yet I don't think either of these things are required to get at least some idea of the intended meaning and certainly don't get the impression that you lack the intellectual resources to do so yourself, should you desire. Agreement, of course, is a different matter.

I will make these observations:

  • Evidence of a break in increases p(staged break in).
  • Evidence that the break in was staged increases p(guilt).

One line of reasoning is this:

  • Evidence of a break in increases p(a break in was staged).
  • Evidence that a break in was staged increases p(guilt).
  • There is evidence of a break in.
  • Therefore, the evidence of a break in increases p(guilt).

This does not follow. Evidence of a break in decreases p(guilt). That is precisely why someone would have motive to stage a break in! Anyone who attempted to increase the extent to which the above fallacious reasoning was applied would be doing something I disapproved of strongly.
