kind of what appeared to be an almost mechanical instruction was given to the effect that, where an armed robbery by the use of a blood-filled syringe is perpetrated, an extra one year's imprisonment should be given on that account above what would otherwise be awarded. Now, the Crown referred to that decision before us, but did not go so far as to say that we should adopt the same yardstick as that which apparently appealed to the Western Australian court. Certainly I would not accede to any submission that we should apply a similar yardstick. All that need be said, I think, is that these kinds of armed robberies, prevalent as they are and easy to perpetrate as they are upon soft targets, need to be dealt with as a particularly horrible species of an undesirable genus, but always having regard to their own facts. They are commonly perpetrated by unstable criminals, usually drug addicts, and calculated to instil into the victim an exquisite sense of anguish and fear of the unknown. It is almost as though the criminal is engaging in a kind of biological warfare that will naturally introduce great apprehension into the mind of the victim. To that extent armed robbery with the wielding of a syringe full of blood is to be viewed sui generis and, in the context of all the other circumstances surrounding the case, dealt with appropriately.
