Botched executions by lethal injection in the USA: Numerous and inevitable

The world was recently shaken by the Romell Broom failed execution: After two hours, and a recount of 18 needles insertions failures, the execution team gave up his execution, facing the reality that they simply couldn't put him to death. The news hit the world as it was the first "failed execution" by lethal injection .

However, looking at history, botched executions by lethal injection are actually numerous (but resulted ultimately in the death of the inmate).
. The needle inserted in Raymond Landry's arm popped out a couple of minutes after the drugs had started to flow and it took officials fourteen minutes to get it back in, for a total execution time of 40 minutes.
. Ricky Ray Rector spent 50 minutes moaning behind a curtain while five execution team members worked on both his arms to find a vein that would accept a needle.                                                                                                                                                                                                                       . Stephen McCoy had such a violent physical reaction to the drugs (heaving chest, gasping, choking, back arching off the gurney, etc.) that one of the witnesses (male) fainted.
. Angel Nieves Diaz, was given a rare second dose of deadly chemicals as he took more than twice the usual time to succumb. Needles that were supposed to inject drugs into the 55-year-old man’s veins were instead pushed all the way through the blood vessels into surrounding soft tissue. A medical examiner said he had chemical burns on both arms.
. There has been dozens of botched executions reported, with prisoners weeping and moaning, technicians eventually inserting needles in the prisoner's neck or foot, drug flow stopping half-way through, or the prisoner convulsing and writhing. 

As Deborah Denno, a professor at Fordham Law School in New York, said the history of lethal injection "has been abysmal. It's been botch after botch after botch."

Despite those alarming issues, the U.S. Supreme Court has upheld executions despite the pain they might cause, but has left unsettled the issue of whether the pain is unconstitutionally excessive.

How could it remain unsettled when executions are carried out without proper medical assistance as doctors are actually forbidden by the American Medical Associations code of ethics to do any action "which would assist, supervise or contribute to the ability of another individual to directly cause the death of the condemned" and "rendering of technical advice regarding executions."

In other words, doctors should be the only persons properly qualified to assist executions but are unable to do so. In fact, Joan Wehrle of the Ohio Medical Board said state law outlines 40 grounds for disciplinary action against doctors, from reprimand to permanent license revocation, including breaches of the AMA ethics code. Holly Fischer, general counsel for the Ohio Nursing Board, said nurses also could face disciplinary action for assisting in executions.

Having a proper medical assistance could be one way to hopefully help reduce the risk of inflicting a cruel and unusual punishment to the inmates.
However, for doctors or nurses to use the skills they learned for healing to kill somebody, could remind us of sad times. "Thats what the Nazi doctors declared" Dr. Jonathan Groner, professor of clinical surgery at the Ohio State University College of Medicine.

 The question remains: If executions cannot be carried out properly,  why should they be then carried out at all?
