12 Recognising that there were a number of factors militating in favour of mitigation of penalty in the respondent's case, including his age at the time of the commission of the offence, the absence of any prior convictions, his plea of guilty, good prospects of rehabilitation and genuine remorse, counsel appearing on behalf of the Director contended that the extreme seriousness of the conduct in which the respondent engaged was simply not reflected in either the term of imprisonment imposed or in the period of immediate incarceration that he was required to serve. In this context, he emphasised the fact that the respondent had armed himself with a weapon with which he was aware he could inflict really serious injury. He then embarked upon a gratuitous and violent attack upon an unarmed and quite intoxicated man for no better reason than his perception that the victim had insulted him. Whilst there was no evidence that Anyieth had sustained some permanent or residual disability, it was apparent that he had suffered very serious head injuries resulting in a significant period of hospitalisation and rehabilitation. Although the respondent was a youthful offender and had to be dealt with as such, counsel submitted, it was necessary for the sentencing judge to regard general deterrence as very important, if not the dominant sentencing consideration in a case of street violence of this type. Even if the sentence of 18 months' imprisonment could be regarded as available in the proper exercise of sentencing discretion, which was not accepted, the suspension of the service of all save six months of it could not, he contended.
