In addition to a sexual harm prevention order, which is important.
There will be many who believe this to be a despicable sentence and others who default to ‘let them rot in jail’ / ‘castrate him’ forms of justice. However, this depends on one’s notion of justice. For me, justice would be ensuring he was not able to harm again (that’s where you can debate the effectiveness of the prevention order) in addition to a punishment (in this case, unpaid work, a lifetime of monitoring by the English equivalent of the public protection unit, and a reputation which will completely alter his once affluent way of life).
The sentence is far from a reasonable one when attempting to achieve revenge, but certainly a just one from a rehabilitation point of view. The moralities of ‘managing’ sexual offences is complex and uncomfortable to navigate. It’s understandable why the ‘throw away the key’ narrative, in its eloquent simplicity is often drawn upon in these cases.
