situation or that, as teenagers, offenders cannot be held appropriately accountable for their conduct in engaging in serious criminal activity.
Secondly, courts 'recognize the potential for young offenders to be redeemed and rehabilitated'. This potential exists because young offenders are typically still in a stage of mental and emotional development and may be more open to influences designed to positively change their behaviour than adults who have established patterns of anti-social behaviour. No doubt because of this potential, it has been stated that the rehabilitation of young offenders, 'is one of the great objectives of the criminal law'. The added emphasis for the purposes of sentencing on realisation of a young offender's potential to be rehabilitated is further justified because of the community's interest in such rehabilitation, not only at a theoretical level, but because the effective rehabilitation of a young offender protects the community from further offending. As stated in R v Lam & Ors,
A primary objective of the criminal justice system is to achieve crime prevention to protect the public. The rehabilitation of an offender should not be seen as a consideration inimical to that objective. Crime prevention to protect the public and the rehabilitation of the offender are interlinked objectives. In sentencing there is thus a broad public interest in taking into account the youth of the offender.
Thirdly, courts sentencing young offenders are cognizant that the effect of incarceration in an adult prison on a young offender will more likely impair, rather than improve, the offender's prospects of successful rehabilitation. While in prison a youthful offender is likely to be exposed to corrupting influences which may entrench in that young person criminal behaviour, thereby defeating the very purpose for which punishment is imposed. Imprisonment for any substantial period carries with it the recognised risk that anti-social tendencies may be exacerbated. The likely detrimental effect of adult prison on a youthful offender has adverse flow-on consequences for the community. As Fox J stated in R v Dixon:
The reasons are obvious enough: the prisoners are kept in unnatural, isolated conditions, their every activity is so strictly regulated and supervised that they have no opportunity to develop a sense of individual responsibility, they are deprived of any real opportunity to learn to live as members of society, their only companions are other criminals...
When, therefore, a court has to consider whether to send a young person to gaol for the first time, it has to take into account the likely adverse effects of a gaol sentence. A distinct possibility, particularly if the sentence is a long one, is that the person sent to gaol will come out more vicious, and distinctly more anti-social in thoughts and deed than when he went in. His own personality may well be permanently impaired in a serious degree. If he could be kept in gaol for the rest of his life, it might be possible to ignore the consequences to society, but he will re-enter society and often while still quite young. His new-found propensities then have to be reckoned with. A substantial minority of persons who serve medium or long gaol sentences soon offend again.[28]
