You're capable of knowing the difference between good and evil at 13. There's no need to treat him as a "child". It may be defined as under 18 for normal purposes, but the people who make these laws know exactly what they're doing, they consulted psychiatric etc. experts, and they decided if a young person 12-17 commits a murder or another big-time felony that is a special case, so they get tried as an adult and serve a proper punishment. They will still get a lower sentence than a full adult 18+ would.
It's not as if they make these laws just because they hate adolescents... they know quite well their brains aren't as developed, less life experience etc. They still have to get justice. I agree they don't belong in an adult prison if they're minors, though. That needs to be sorted.
All this about "brain doesn't develop fully until 23-25" well it's sufficiently developed to make decisions, it doesn't have to be complete
This is why I believe in proper juvenile justice. (not because I'm a right wing bigot as some people think, which I ain't)
When I was at first year secondary school there were a core of 5 kids- just calling them by numbers here- who were always causing trouble and they weren't punished properly. I went to SMT because they were bullying me and a few of my friends just for being intelligent (and spots/glasses in some of the others, but mainly for being in top set and having >95% attendance). They were also consistently disruptive but instead of expelling them or clamping down they were practically ignored.
I later found out (2 quickly who I befriended and got on with afterwards, the others over the course of some years):
1-in care since age 4, mum died and dad incapable of looking after him on his own,
2-(left school year 8) went into care & changed school, massive sexual abuse from father
3-(left school year 9) went to mother's & changed school, sexual abuse from father
4-with gran on section-20 since 5 because father died in suspicious circs and mum had a massive mental breakdown, she was still in a psychiatric home when the girl was 19 when I last heard from her.
5-terrible upbringing all round, was in my form but rarely saw her as she was bottom set for everything, yet her dramas were well known- bulimia, OD's, attempted suicide, first sex at 12 with older teen boy, etc.- lived with grandad and everyone thought dad had abused her but she wouldn't say even to police
Basically Senior Management were exculpating people for their misbehaviour just because they'd had a very bad home life, how unfair is that for the other pupils in their classes and the ones they bully?
The headmistress sounded like a proper Owen Jones/ Camilla Batmanghelidid/ Will Hutton before these people were even writing their anti-responsibility trash. She was alright, well into the higher rate tax band, 5 bedroom house and her husband was a fucking professor. But we had to get through our GCSE and A levels and then onto work or university and the disruptors weren't helping. So she was a right hypocrite.
Pontificatin' about "compassion" and "inclusion" like a left-wing reactionary maniac- when class teachers were EXCLUDED from being able to run an uninterrupted lesson, the bright pupils were EXCLUDED from reaching their potential, and there's nothing compassionate about making other people suffer (it's the opposite.)
/conservative rant over. Next rant will be a left-wing one against exploitative interest charged by "pay weekly shop" and cash advances... because I'm not a politician. I think if you care about the poor, "left-wing" economic policy is obviously better but "right-wing" education policy where you learn a non-dumbed-down curriculum, take tough exams on it, and no-one is allowed to misbehave is better too. Otherwise it's the less well off that suffer coz the rich would still have advantages even if private schools were (per impossibile) all banned
