Bring back firing squads?

From The Plague, by Albert Camus:

"Have you ever seen a man shot by a firing squad? No, of course not; the spectators are hand-picked and it's like a private party, you need an invitation. The result is that you've gleaned your ideas about it from books and pictures. A post, a blindfolded man, some soldiers in the offing. But the real isn't a bit like that. Do you know that the firing-squad stands only a yard and a half from the condemned man? Do you know that if the victim took two steps forward his chest would touch the rifles? Do you know that, at this short range, the soldiers concentrate their fire on the region of the heart and their big bullets make a hole into which you could thrust your fist? No, you didn't know all that; those are things that are never spoken of… Decent folks must be allowed to sleep easy o' nights, mustn't they?…

…When I spoke of these matters they told me not to be so squeamish; I should remember what great issues were at stake. And they advanced arguments, often quite impressive ones, to make me swallow what none the less I couldn't bring myself to stomach. I replied that the most eminent of the plague-stricken, the men who wear red robes, also have excellent arguments to justify what they do, and once I admitted the arguments of necessity and force majeure put forward by the less eminent, I couldn't reject those of the eminent…

In any case, my concern was not with arguments. It was with the poor 'owl'; with that foul procedure whereby dirty mouths stinking of plague told a fettered man that he was going to die, and scientifically arranged things so that he should die, after nights and nights of mental torture while he waited to be murdered in cold blood. My concern was with that hole, big as a fist, in a man's chest. And I told myself that meanwhile, so far anyhow as I was concerned, nothing in the world would induce me to accept any argument that justified such butcheries. Yes, I chose to be blindly obstinate, pending the day when I could see my way more clearly."
