What I don’t understand is in a world where humans have become so good at killing each other that we can’t come up a truely humane way to kill someone.
The electric chair seemed like a good idea, but then people started catching on fire, needing multiple zaps etc.
Hanging was great, unless the rope was too short and you dangled and suffocated. Or too long and it popped your head clean off. Just right the neck snapped, instant numbness and death.
Firing squad certainly isn’t instant or painless.
Gas chamber, while the condemned holds their breath until the last possible second seems cruel and unusual.
Lethal injection is probably the best bet, but it may need to be adjusted to take advantage of better killing drugs.
