Several states are considering new methods for carrying out the death penalty. The old three-drug-cocktail mix of sodium thiopental - pancuronium bromide - potassium chloride was the drug choice combo to provide a quick and painless execution. This method was favored over the more barbaric use of the electric chair, gas chamber or firing squad.
Now that some of these drugs are in short supply or even unable to be sold in the U.S. states are looking to using other drug combinations. Just this past Wednesday the Missouri Supreme Court allowed for the use of the drug propofol, the state had been considering bringing back the electric chair.
Ironically the hang up on finding a suitable means of execution seems to be being able to provide a quick and painless method. If there is one thing you can say about the death penalty people is that they are a very kind and considerate lot.
I don't have a vote but maybe it is time to bring back the spectacle of the guillotine in the town square. It seems as though almost everyone in attendance in those days enjoyed themselves.
