Make the punishment fit the crime!

The ringleader of a gang that raped, drugged and forced a 14-year-old girl into prostitution was sentenced to 9 years in jail. On appeal, the sentence was reduced to 7 years. The rest of the accused men received sentences ranging from 8 months to 4 years.
Meanwhile, an antiques dealer who acquired a stolen copy of Shakespeare's first folio and allegedly hoped to sell it for around £1m was jailed for 8 years.
Ian Huntley who murdered two 10-year-old girls in 2002 and was subsequently jailed for life has been advised that he should not pursue his intention to sue the Prison Service for failing in their duty of care after his throat was slashed by another inmate. If the case were to proceed it could cost tax payers more than £1m in legal aid fees. If successful he might be awarded as much as £95,000. It is being strenuously stated that no compensation will be forthcoming but the prisoner is within his rights to proceed – that's if his fellow inmates, said to be enraged by his intention, don't despatch him first.
So, the interested bystander from another planet might assume that in the UK, at least, an old book is worth more than the life of a young girl and that a convicted murderer can sue his jailers because they haven't protected him from harm. Where is the common sense in this Alice in Wonderland series of events?
