Some people would prefer to have a dramatic, ceremonial exit. I would definitely prefer to be executed by hanging than to do something antimedical to my breathing or my blood while strapped down. Forced immobility is a form of torture in itself, and some people find it far more horrific the notion of undergoing internal damage from poisons or being deprived of air than to have a quick drop and broken neck. I would rather die from an external force causing a traumatic physical injury than die from an internal corruption of my biological systems.
I think those condemned to death should get a choice of execution methods from a set of several proven to work.
That's actually a great point.
Not all people are alike, and I don't know if we can actually say, "This here is the very best of all methods of dying." I suppose the most humane way to do this, if do this one must, is to have a whole array of methods, and the guy on his way out gets fully informed in full detail about each method, and then makes his considered choice.
That's probably the most humane option, to give the guy that choice.
eta: Yeah, it's bizarre actually, to on one hand allow for killing people like this, and on the other hand to think of being humane about it. But still, within those bizarre parameters, I suppose this is the most humane solution, to offer the guy a whole array of options, and leave him to make the choice.
etaa: Absolutely, including even grisly but sureshot methods, like that weight dropping on the head thing of Joe's, as well as the decapitation thing those weirdos in Japan apparently used to go in for, or maybe the guillotine, make it a nice big menu. Including hanging as well, sure.
