Canada is currently considering whether or not to make it a separate crime to attack a woman and kill her unborn child. Currently, a fetus is not considered to be a human and therefore the perpetrator can only be charged with assault against the pregnant woman. I was just reading the laws of Hammurabi written circa 1726 BC and came across this section:
209 If a seignior [freeman] struck a(nother) seignior’s daughter and has caused her to have a miscarriage, [fn Lit. “caused her to drop that of her womb (her fetus)”] he shall pay ten shekels of silver for her fetus. 210 If that woman has died, they shall put his daughter to death. 211 If by a blow he has caused a commoner’s daughter to have a miscarriage, he shall pay five shekels of silver. 212 If that woman has died, he shall pay one-half mina of silver. 213 If he struck a seignior’s female slave and has caused her to a have a miscarriage, he shall pay two shekels of silver. 214 If that female slave has died, he shall pay one-third mina of silver.

I think we can conclude that 3500 years ago killing an unborn child was considered a separate crime from attacking a pregnant woman. I don’t think we can let the abortion debate dictate whether or not we enact this type of law because there is certainly a precedent.
