My beef with the courts is that I believe it failed to find Terri's wishes. I will concede, of course, all of the procedural steps you noted were in fact carried out. Interested people will look at the evidence before the court, and draw their own conclusion.
... the decision was supported by competent evidence. The countervailing evidence was admitted, and it was addressed.
Yes it was. And the outcome was the wrong one, in my opinion. At that is my beef. It has nothing to do with supposition, innuendo, and unfounded allegations, as you assert.
I do know that Terri's own lawyers, one of whom was appointed by Jeb, found no basis for the abuse allegations. Terri's own lawyers practically begged the Schindlers to present medical testimony more credible than what they relied upon (one even wondered why the most qualified doc they hired [Webber, I think?], whose affidavit was used to actually get a new hearing, did not provide testimony at the hearing).
We also know that the Schindlers conceded FOR YEARS in the court process that Terri was PVS. That didn't change until some of the more questionable characters in these events got involved.
