I find firing squads a huge backwards step.

I don't "not agree" I just know it isn't the case, Kizzy. I'm sure all of the anaesthetists - who train for ten to twelve YEARS to become fully qualified - would disagree with the statement that it's "not hard to render someone unconscious".

It's a slightly moot point as I actually don't really agree with the death sentence at all. But if it must be done, there are much quicker and completely painless ways to carry it out.

The lethal injection became popular because it's "more modern seeming" and "cleaner". It's certainly preferable to the electric chair which was in common usage in the US. However, just because it's the cleanest and quietest way does not mean it's necessarily the most humane.
