Something that bothers me is that poisoners are not usually caught with their first victim. It almost always involves a second death that appears to be from natural causes but arouses suspicion (lost two spouses in four years?) or an accidental poisoning of a third party (or the poisoner). So I can't help but wonder how many murderers use poison to kill one victim, never do it again, and are never caught.
I'm not anti-Christian. I'm anti-stupid.
