Lethal injections, and executions, are never necessary.. It is in the best interest of everyone for everyone to abandon the concept en total.

Totally agree, but until we abolish the death penalty I’d rather have it done humanely.

There's the argument to be made; which would people be more likely to protest and try to end the practice of:

Death row inmates falling asleep and not waking up.

Death row inmates being drawn and quartered (bit of an extreme example).

(for those that don't know "drawn and quartered" involves four plow horses, some rope and an axe or two)
