Just finished reading this. There are no words for how upsetting it is to see such a gross misuse of medicine. Wildly unethical actions taken by so many involved.
State sanctioned torture pure and simple. The fact that they turn death row inmates into human chemistry sets without knowing exactly what will happen going into it is barbarism at its worst, if I recall there were something like 3 other incidents that same year. Regardless of how you feel about those sentenced to death, it's absolutely cruel and unusual punishment. I'm sure some people will applaud that suffering they went through but the justice system should dole out swift and decisive punishment, not satisfy some fucked up sense of vengeance.

Again story in question regard what comes of states who decide to say fuck it and use alternative drugs instead, urge reading it to get a better grasp of the outcomes that have been repeated NUMEROUS times now.
