"[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 reeks on the lives of the white collar criminal and his or her family, may have a tendency to distract attention from the importance of general deterrence or 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. ... [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."
