Put them in a chamber, pump in nitrogen and wait 30 minutes. It's painless and certain, requires no medical skills to administer and the gas is dirt cheap.

But you'd still probably want to strap them to a gurney, in case they tossed a fit after the hatch was dogged down.

We need a disintegrator. Instant, painless... poof!

Actually toss 'em into a smelter, or a modern coal turbine power plant furnace. Flash evaporation. Plus, at least we'd get a half a KWh out of 'em. They keep bitching about energy costs...

Absolutely.

This whole argument is so retarded, as if it were some great intellectual puzzle how to dispatch someone quickly and without suffering (not that I have anything against a littler suffering in some of these cases. In fact, I am liking the IV cocktail much better now that this possibility of extreme suffering while paralyzed has been introduced. It is probably a bogus concern, but I bet it is causing some bad dreams on death row. They should be having bad dreams.)
