following the botched execution -- what should be the way to execute some one?

60. Captive bolt to the lower skull. Seriously.

It's been proposed many times and is inarguably the most humane way to purposefully end a life, but it never goes anywhere because it involves a bit of blood.

Basically, a high speed bolt punched into the rear of the skull. This bolt would crush the lower part of the brain, almost instantaneously ending life functions while simultaneously severing nerve connections to the thalamus, which handles pain. The part of the brain that feels pain would be destroyed before the nerves could even send a pain signal to it, so the roughly 1/2 of a second that it would take for the rest of the brain to shut down would be completely painless.

I don't agree with the DP, but if you want the most "humane" method, it's hard to find a better solution. Simple, effective, instant, and 100% painless.
