Anderson,
Read the affidavits, examples as put forth in RKAB post are there in black and white as to some of NC's behaviors, as I stated in another post, it is all "he said, she said". Of course NC did not deserve to be murdered, I do not think anyone meant to imply that, I certainly did not. Simply put she had her controlling behaviors as well, but wait, she was a human being and some less than desirable behavior comes from all us, BC and NC included.
Of course I have read the affidavits. In some cases there is first-hand information that is related to BC's behaviour (e.g., Krista's affidavit).
We have established that BC and NC had a bad relationship. That would be the only reason to speculate on NC's behaviour. Can you think of another reason to do this? We all agree that none of us really have any idea about what their relationship looked like on the inside.
However, RKAB's comments are based on her experience with BC. It is very different for her to make a comment about BC than it is for one of us to speculate on this issue.
BC is also the person that MAY have murdered NC. It makes sense to discuss BC's behaviour, because it is relevant to the ongoing investigation.
