Everyone must agree, this is a hugely emotive issue, and there is no simple solution. The papers favour the 'vigilante' angle, and there is the notion that the young men's (and that is what they are now) identities will be made known, and revenge will be taken. But how often are released criminals ever found and is revenge taken? It's a thought, and usually remains just that. Regardless of the emotion of the issue, the law must be followed - our laws are what make us civilised, without the framework of legal process, civilisation would degenerate.
As for 'freedom' - just how 'free' will these two people ever be? Doomed to carry the wight of their crime in secret for the rest of their lives - it's no substitute for a child's life, but neither is it 'freedom' as I understand the word.
