Well, Baill. You answered that question like you have been asked it before....LOL Alright, I have another one for you.......
When they kill someone via Lethal Injection, why do they sterilize that needle they use?
Two reasons:
Most important reason is in case the medical staff gets accidentally pricked from the needle.
Also, there is always a possibility that there will be a last minute stay in the execution, after the needle is inserted bust before the poison is injected.
