People generally agree that nitrogen (or any inert) gas asphyxiation is a relatively painless and peaceful way to go. People have been using it for (animal and human) euthanasia for years without incident. Seems appropriate, right?

So how did it work in capital punishment scenario the first time around? The guards slapped the face mask on the condemned. Then they asked them for their last statement. Quote: "Mffmfmf, Mffafam fmfmfm mfffmfmf mf mfmf f mfmf mfffmfmmf. Mfffm mfm mfm mfmfffmfmf mf. Mfff mff mf mff." (Transcribed as: "Tonight, Alabama causes humanity to take a step backwards. Thank you for supporting me. Love all of you.") Then they opened the gas valves. It took too long. ...OK, it's time to pause now, let's see how many problems you can spot with this procedure.

Problem: They're continuing to use "medical" and "painless" and whatnot procedures, administered by unqualified staff, on unwilling participants. Look, I'm not an advocate of death penalty at all and I think it should be abolished everywhere, but even I know that the guillotine designers were up to something. You need to minimise the amount of fuck-ups at all levels.
