58 Although, as the learned sentencing Judge said, it provides no excuse or acceptable explanation for the applicant's involvement, it was accepted that once it became clear to the applicant what his co-offenders planned, the applicant did not think of withdrawal as he should have done, but only of how his involvement might be managed in such a way as to minimise the prospect of harm occurring to any victim upon whom the offences were to be committed, offences from which he was to gain nothing. While that is not an acceptable explanation for his involvement, it is understandable, particularly when one is speaking of such a decision taken by an obviously naïve young man just three months after his 18th birthday, on the spur of the moment when he was already caught up in the process of driving his co-offenders to the place where they wished to confront those from whom they sought to obtain money. It was not on that basis so much a matter of bravado, as surmised by the applicant's father, as appalling misjudgment which allowed him to be not only carried along by the events of the night, but also to become centrally involved in their perpetration.
