Because Canadian Law makes so much sense...
When child becomes human being
- 223 (1) A child becomes a human being within the meaning of this Act when it has completely proceeded, in a living state, from the body of its mother, whether or not
- (a) it has breathed;
- (b) it has an independent circulation; or
- (c) the navel string is severed.
- Marginal note:Killing child
(2) A person commits homicide when he causes injury to a child before or during its birth as a result of which the child dies after becoming a human being.
So you can pummel a pregnant woman - and as long as the the child dies inside the woman who is pregnant - you can't be charged with a homicide related to the death of the child -- just the assault on the woman who was carrying the baby...
Oh Canada, you really make me want to puke these days.
