Why not just a massive morphine overdose? Why does it have to be so complicated.
Oh yeah. The Govt. Never mind.
Nitrogen Asphyxiation
Strap the condemned down
Afix a brain wave monitor
Hook up a medical breathing mask to a 99% pure nitrogen supply
flow 1.1 atmospheres to the breathing mask
Wait for brain waves to go flat for 5 min.
Condemned just goes to sleep.
morphine OD, fentanyl, pure nitrogen or CO2, public hangings, so many cheap ways to do executions but instead most States rely on expensive bunches of drugs that are hard to source...
