They have lost a child. That is worse any jail time you could mandate
Im not saying they should be jailed, obviously no one has any idea what has happened in this case.
But in general terms, I hate this argument. It gets said sometimes in threads where someone’s dangerous dog has killed their toddler “oh we can’t punish them, they’ve been through enough”. No. That’s absurd. If someone drove drunk, crashed their car, and killed their child in the back, would we say “poor thing, they’ve suffered enough, a death by dangerous driving charge would be just mean”.
As I said, I’m talking generally, not about this specific case where no one has details (nor do I think we are entitled to those details). But if the details are that they were in the wrong in some way, legally speaking, I would not agree at all with the idea that they shouldn’t be punished because losing a child is punishment enough.
