Death isn't not messy, regardless of what method is used to induce death. In death the body totally relaxes, and guess what? It gets real pissy and shitty!rotor,
NOT a JOKE. = There have been SEVERAL civil cases filed for condemned inmates that wanted the FDA to certify that the drugs were "safe & effective for the intended purpose".
That is at least HALF obviously STUPID as a drug cocktail intended to KILLED inmates is NOT "SAFE".
OTOH, if it DOES kill the inmate, it was EFFECTIVE.
Personally, I favor HANGING (Frankly, I would prefer if the hanging was in the county where the felony occurred, as it once was in Texas.) as a proper hanging is QUICK, CLEAN & ALWAYS KILLS.
(My SOLE objection to death by firing squad is that it is usually MESSY to clean-up after, just as beheading IS.)
