Turns out the chemical companies they were buying the death chemicals from stopped producing them, and every medical professional began refusing to administer them, and instead of putting a stop to executions this has resulted in states making death chemicals in tiny unregulated laboratories and having cops without proper training administer them, which means that almost every executed prisoner suffers needlessly while completely paralyzed before dying slowly instead of quickly and painlessly as originally intended.

Oh and they also harvest the organs of their prisoners.
