Disconcerting reports about what transpired during recent Alabama execution

A press report on the July 28 execution of Joe Nathan James in Alabama, reprinted in this post, noted that the "execution began a few minutes after 9 p.m. CDT following a nearly three-hourts have started to fill in some ugly details of what transpired during this delay.  For example:

From The Atlantic, "Dead to Rights: What did the state of Alabama do to Joe Nathan James in the three hours before his execution?":

James, it appeared, had suffered a long death. The state seems to have attempted to insert IV catheters into each of his hands just above the knuckles, resulting in broad smears of violet bruising.  Then it looked as though the execution team had tried again, forcing needles into each of his wrists, with the same bleeding beneath the skin and the same indigo mottling around the puncture wounds.  On the inside of James’s left arm, another puncture site, another pool of deep bruising, and then, a scant distance above, a strange, jagged incision, at James’s inner elbow.  The laceration met another cut at an obtuse angle.  That longer, narrower slice was part of a parallel pair, which matched a fainter, shallower set of parallel cuts.  Underneath the mutilated portion of James’s arm was what appeared to be yet another puncture — a noticeable crimson pinprick in the center of a radiating blue-green bruise. Other, less clear marks littered his arm as well.

From AL.com, "Joe Nathan James ‘suffered a long death’ in botched Alabama execution, magazine alleges":

Alabama prison officials spent hours searching for a vein that could be used to deliver lethal drugs in the execution of Joe Nathan James on July 28, according to a recent article in the Atlantic.  Staff punctured his hands, wrists and elbows several times before finally cutting open his arm to expose a vein, according to reporting by Elizabeth Bruenig.

Bruenig attended an independent autopsy performed several days after James’ death and funded by the human rights group Reprieve U.S. “James, it appeared, had suffered a long death,” she wrote.

From The Guardian, "Alabama subjected prisoner to ‘three hours of pain’ during execution – report":

Alabama’s execution of Joe Nathan James Jr last month may have taken longer than any other lethal injection in recorded American history, and no death penalty ever administered in the US may have taken quite as long, according to an analysis by a human rights organization.

An examination by Reprieve US of James’s execution estimates that it took Alabama officials between three and three and a half hours to carry out the lethal injection, a duration that the organization argues violates constitutional protections against inhumane punishments.
