That’s how the law would treat an adult. “That’s not defending your home, that’s murdering a man who isn’t a threat” is what the adult would be told. They’d want a very good lawyer, they also would have wanted to aim better so there was only their side of the story

We don’t apply the law like that against children* because children don’t have the ability to control themselves or think before acting that adults have.

Have a bit of empathy for the kid.

*Except when it’s very newsworthy
