' ... what is fitting is that a convicted prisoner should be sentenced, not simply and indiscriminately for every act that can be singled out and brought within the compass of a technically identifiable conviction, but for what, viewing the circumstances broadly and reasonably, can be characterised as his criminal conduct. Sometimes, a single act of criminal conduct will comprise two or more technically identified crimes. Sometimes, two or more technically identified crimes will comprise two or more courses of criminal conduct that, reasonably characterized, are really separate invasions of the community's right to peace and order, notwithstanding that they are historically interdependent; the courses of criminal conduct may coincide with the technical offences or they may not. Sometimes, the process of characterization rests upon an analysis of fact and degree leading to two possible answers, each of which, in the hands of the trial judge, could be made to work justice. The practice of imposing either concurrent or consecutive sentences cannot avoid creating anomalies, or apparent anomalies, from time to time. What must be done is to use the various tools of analysis to mould a just sentence for the conduct of which the prisoner has been guilty. Where there are truly two or more incursions into criminal conduct, consecutive sentences will generally be appropriate. Where, whatever the number of technically identifiable offences committed, the prisoner was truly engaged upon one multi-faceted course of criminal conduct, the judge is likely to find concurrent sentences just and convenient.'
