Due process applies to civil probate issues, as well as criminal proceedings. I would point out that Congress had the power to order the reinsertion of the feeding tube, via the statutory relief of a mandatory injunction. They did not. Therefore, I find that Congress is culpable here as well. It's easy to blame one person for all this, but that oversimplifies, and worse, it prevents us from making real fixes to the system.
Once again, you misunderstand. I blame everyone from the President on down for this, including the LEOs who helped guard the murderers while they committed the crime.
And ultimately, the whole country bears the responsibility for remaining criminally and willfully ignorant and complacent.
