How do you KNOW they would have pursued it. I had read that when the Schindlers found out about Terri's bone scan, the brought it to the attention of the Sheriff. However, the Sheriff refused to investigate, supposedly because it was too old. They don't "HAVE" to pursue anything, and they sure as heck haven't! They all seem to be tied together; the judge, the lawyer, the hospice, the Sheriff's department; anyone that could help Terri. Check it out - it's all out there.
Well, as you know, there are such things as statutes of limitation. As I understand your view of the 1991 nuclear imaging report, it is that the report constitutes evidence of batteries upon Terry prior to her strokes. It is true that those would be barred by the statute of limitations.
By my comment was addressed to the contention that the husband was (currently) trying to 'murder' his wife. If true, that would be a crime and no statute of limitations would prevent a grand jury or prosecutor from investigating and charging it.
Now your last sentence reflects the 'conspiracy theory of history'. I'm sorry I just don't believe in such large conspiracies. My experience as a prosecutor was that any conspiracy involving more than two conspirators couldn't be maintained. BTW, what's their motive? Sharing in insurance proceeds? Come'on.
