They spent insane amount of cash to kill the guy, yet even then they keep failing to do just that.
Either just give him the heavily tested (on animals) and scientifically supported nitrogen, if you really need to kill him that bad or just send him to a damn prison and forget about him.
Issue is, this isn't the first time I'm reading about someone complaining about the execution method.
The guy's lawyers were raising complaints about it as well, most likely to try to postpone the execution.
Every day the guy's alive costs the state money, it costs the time of his lawyers, judges and these "experts" and for what? To postpone his death a couple months? To have him get an arguably more painful and error-prone executiom method?
It's just a waste of resources. Either kill him if they must or stash him away for the rest of his life in a high security prison, this circus is unproductive for all parties involved.
