"The court does not have to wait for somebody to cause injury before invoking the IPP provisions."
"14. Returning to the exercise of the court's discretion, or more accurately, its judgment, whether a sentence of imprisonment for public protection should be passed when the necessary criteria are established, the court is entitled to and should have in mind all the alternative and cumulative methods of providing the necessary public protection against the risk posed by the individual offender. For example, structured around a determinate sentence, or indeed an extended sentence under section 227 of the Act, which we shall shortly address, a sexual offences prevention order, with appropriate conditions attached could form part of what we may colloquially describe as the total protective sentencing package. Apart from the discretionary sentence of life imprisonment, imprisonment for public protection when the necessary conditions are fulfilled, is the most draconian sentence available to the court. If they are, we re-emphasise that the primary question is the nature and extent of the risk posed by the individual offender, and the most appropriate method of addressing that risk and providing public protection. If what we have described as the overall sentencing package provides appropriate protection, imprisonment for public protection should not be imposed. ... 20. ... As we have emphasised, imprisonment for public protection is the last but one resort when dealing with a dangerous offender and, subject to the discretionary life sentence, is the most onerous of the protective provisions. In short, therefore, if an extended sentence, with if required the additional support of other orders, can achieve appropriate public protection against the risk posed by the individual offender, the extended sentence rather than imprisonment for public protection should be ordered. That is a fact specific decision."
