You know who invented the "Lethal Injection" (which by the way is now the most popular way of the death sentence)? Fred Leuchter. Any idea who that is? He was in charge of finding a new way to kill people "unworthy of life" in Auschwitz. Lethal injection is a Nazi practice, and for us to call it human is ironic beyond belief. Lethal injection sometimes doesn't even come to standards for putting animals to sleep.
Anyone even know what happens during the process? First your put to sleep by a drug called Sodium thiopental, it lasts about a minute. After that you get a dose of Pancuronium bromide, which paralyzes your respiratory system. Finaly you get dosed with Potassium chloride, which forces you into cardiac arrest. Sounds simple and harmless, but the system is flawed.
The correct dosage amount of the first drug depends on you. Everyone has a different amount that works for them. Autopsy's have shown that some prisoners have not been dosed enough for them to loose consciousness, but only to be non-mobile. So some prisoners have been fully aware of whats happening and probably suffered through not being able to breath and a significant amount of pain near the end. The only person lethal injection is human for, is the person administering the drugs.
Know the facts.
