A question for those who think a 12 year old?

[Essex Lewis]

Rape of a child is a Very Serious Crime, nearly as serious as Murder.

So of course he should've been given a "Custodial Sentence", and because he's 12 he wouldn't be sent to Jail or a Y.O.I, but a Secure Children's Home, which is a closed/secure environment, but still completely different to Prison, where he could get the help he needs, but still be "PUNISHED".
He needs to grasp the enormity of his crime, otherwise he will Re-offend.

If we let him off, why not let off Child Murderer's too?
Should we have given John Venables, Robert Thompson (James Bulger Murderers) and Mary Bell (Strangled two toddlers to death in Newcastle) Custodial Sentences - or just given them a slap on the wrist because they were 10/11 year olds?
