"[I]n the case of white collar crime, the lives of the offenders and their families will frequently have been devastated by the consequences of discovery and punishment. The present case is a very good example. It would be difficult not to feel great sympathy for the respondent's wife and family and, indeed, for the respondent himself. But I think there is a serious risk that the consequences of discovery and punishment, and the havoc that a custodial sentence usually wreaks on the lives of the white collar criminal and his or her family, may have a tendency to distract attention from the importance that general deterrence ought to carry in the imposition of sentences for crimes such as the present. ... Whatever the motivation, offences of the kind here in question almost invariably involve a carefully calculated course of conduct over a long period, repeated deliberate acts of dishonesty, substantial amounts of money, and, frequently, losses (often tragic in their impact) to large numbers of small investors. The offender often holds a position making it possible, or has the ability, to disguise or camouflage the conduct in question. Detection is difficult, the investigation of the crime usually lengthy and very expensive, and the problems of trial and proof will frequently be extreme. ... [T]he element of general deterrence will usually carry particular significance in sentencing for crimes such as the present, both in relation to the total effective sentence and the non-parole period; together with a requirement for strong denunciation by the sentencing court. For persons first contemplating corporate criminality, a sentence which requires an offender to spend a substantial term in actual custody by virtue of the non-parole period fixed, is, in my view, much more likely to focus their attention and have real deterrent impact than a longer head sentence, much of which is likely to be served on parole after the offender's release from custody. If this view be correct, to fix an unduly short non-parole period would, in cases such as the present, be quite subversive of the whole concept of general deterrence ..."
