Found the death penalty for messing with the delivery of mail in the Annals of Congress. I believe it was the first or second Congress which passed that law.
Jim Kalb wrote a piece while at Yale on colonial law which I can no longer find on the internet. Fascinating. Pennsylvania had some draconian punishments. The punishment for homosexuality was worse than for rape. Flogging, then ten years and sometimes the death penalty as I recall. Rape was, again from memory, five years.
We never learned this stuff in history class. I need to keep reading.
