Because what this case tells us, ultimately, is that people's lives are messy. Stuff doesn't happen according to a smooth and well considered plan.
And the people who have to pick up the pieces are themselves constrained by the laws that govern them.
In this case, as tragic as it must be for the mother, the baby is being considered with all the attention to its rights and needs as any other baby born in the UK.
For that, personally, I am thankful.
