"My child would be my first priority, if I am being 100% honest. I would do whatever I could to avoid leaving her without a mum for ten years, or however many I thought I would have to serve. "
But logically then you would also do your best to evade facing justice as a Brit in Britain,
if you had accidentally driven on the wrong side of the road and killed someone,
whether a teen on a motorbike,
or a baby in a pram
So the diplomatic immunity is irrelevant if you think anyone would choose to evade justice if they could.
seaweed would you hand yourself in if you accidentally killed a baby and thought you would go to jail,
but were sure you couldn't otherwise be traced as the guilty party ?
I suspect many people wouldn't, in rl.
