"...I am satisfied that the normal period of licence would not be sufficient to prevent the commission of further offences or secure your rehabilitation. I consider that you represent a danger to young boys, and the reasons why I am imposing the extended sentence."
"In all cases the court should consider whether a particular extension period can be justified on the evidence available. A long extension period should usually be based on a clear implication from the offender's criminal record or on what is said in a pre-sentence report or a psychiatric report. The objective, where possible, should be to fix the length of the extension period by reference to what can realistically be achieved within it."
