41 I regard this as a clear case of a manifestly inadequate sentence to the point of error. It is well established that arson is a serious crime. It is, generally speaking, and subject to all the circumstances of the case, among the most socially dangerous and disturbing to the community of all crimes which do not involve personal violence, because it is so easy to commit, is so potentially dangerous to property and sometimes life, and is often so difficult to control. Honner v R unreported 35/1977, per Neasey J, with whom Green CJ, agreed, at 3. A sentence that included retribution and denunciation in particular, and also general and personal deterrence, was demanded. The damage caused by the fire was considerable and the motivation for the crime made this a particularly bad case. For an arson committed in similar circumstances, that is to say an arson committed with pre-meditation to destroy forensic evidence that could lead to detection following a burglary and stealing, this Court, in Targett v R unreported A74/1996, had no hesitation in concluding that three years' imprisonment for an aider of an arson that caused $150,000 damage was not manifestly excessive for a 23-year-old offender who pleaded guilty. No doubt some of the length of the sentence could be accounted for by the fact that the offender had an appalling record, mainly for dishonesty.
