Executed Killer Dennis McGuire Gasped And Snorted For 15 Minutes Under New Lethal Drug Combo

Short form: now that drug companies are making it difficult for states to obtain the usual crop of Lethal Injection drugs for executions, states are tinkering with recipes. And apparently the results aren’t always quite so quick and clean. But… come on, it’s not really that big of a challenge. If executions are to be painless, a few options *immediately* spring to mind:

1) Gunfire to the brain stem

2) Overdose of morphine

3) Put a mask on them, and feed them pure nitrogen or freon. From what I’ve read, thre have been numerous industrial accidents where people have gotten stuck in rooms filled with pure nitrogen or freon, and they have simply, quickly, quietly slipped into unconsciousness, and if not dragged out in a minute or two, slipped into death. Unlike CO2, breathing pure N2 doesn’t bother your lungs, so it doesn’t hurt and you don’t cough and choke.

Nitrogen would seem an obvious and easy one. Anybody know of a reason why this would be problematic?
