This is factually incorrect. There's something called the 5th Amendment which states that one shall not be held to account for infamous crimes without a indictment or presentment, further it says that they will not "be deprived of life, liberty, or property, without due process of law;"
Then there's something called the 6th Amendment which says that in all criminal prosecution the accused has the right to a jury trial.
Then there's the 8th Amendment which prohibits "cruel and unusual punishments."
Oh, wait, I forgot, things like Constitutions don't constrain governments but are instead interments to bludgeon people with... carry on.
Actually, it is factually correct.
While I agree with your cites, that does not mean that the jurists do not have unqualified immunity.
They do - and that is, unfortunately, a big reason that they act as they do.
What I think should be done would probably get me banned here.
