of a breach of peace. This is so, in part, because the risk that such a harm will occur differs depending on the underlying offense with which it is connected; and also because, in part, the relationship between punishment and multiple harms is not simply additive. The relation varies depending on how much other harm has occurred. Thus, it would not be proper to assign points for each kind of harm and simply add them up, irrespective of context and total amounts.
The larger the number of subcategories of offense and offender characteristics included in the guidelines, the greater the complexity and the less workable the system. Moreover, complex combinations of offense and offender characteristics would apply and interact in unforeseen ways to unforeseen situations, thus failing to cure the unfairness of a simple, broad category system. Finally, and perhaps most importantly, probation officers and courts, in applying a complex system having numerous subcategories, would be required to make a host of decisions regarding whether the underlying facts were sufficient to bring the case within a particular subcategory. The greater the number of decisions required and the greater their complexity, the greater the risk that different courts would apply the guidelines differently to situations that, in fact, are similar, thereby reintroducing the very disparity that the guidelines were designed to reduce.
In view of the arguments, it would have been tempting to retreat to the simple, broad category approach and to grant courts the discretion to select the proper point along a broad sentencing range. Granting such broad discretion, however, would have risked correspondingly broad disparity in sentencing, for different courts may exercise their discretionary powers in different ways. Such an approach would have risked a return to the wide disparity that Congress established the Commission to reduce and would have been contrary to the Commission’s mandate set forth in the Sentencing Reform Act of 1984.
In the end, there was no completely satisfying solution to this problem. The Commission had to balance the comparative virtues and vices of broad, simple categorization and detailed, complex subcategorization, and within the constraints established by that balance, minimize the discretionary powers of the sentencing court. Any system will, to a degree, enjoy the benefits and suffer from the drawbacks of each approach.
A philosophical problem arose when the Commission attempted to reconcile the differing perceptions of the purposes of criminal punishment. Most observers of the criminal law agree that the ultimate aim of the law itself, and of punishment in particular, is the control of crime. Beyond this point, however, the consensus seems to break down. Some argue that appropriate punishment should be defined primarily on the basis of the principle of ‘just deserts.’ Under this principle, punishment should be scaled to the offender’s culpability and the resulting harms. Others argue that punishment should be imposed primarily on the basis of practical ‘crime control’ considerations. This theory calls for sentences that most effectively lessen the likelihood of future crime, either by deterring others or incapacitating the defendant.
Adherents of each of these points of view urged the Commission to choose between them and accord one primacy over the other. As a practical matter, however, this choice was unnecessary because in most sentencing decisions the application of either philosophy will produce the same or similar results.
In its initial set of guidelines, the Commission sought to solve both the practical and philosophical problems of developing a coherent sentencing system by taking an empirical approach that used as a starting point data estimating pre-guidelines sentencing practice. It analyzed data drawn from 10,000 presentence investigations, the differing elements of various crimes as distinguished in substantive criminal statutes, the United States Parole Commission’s guidelines and statistics, and data from other relevant sources in order to determine which distinctions were important in pre-guidelines practice. After consideration, the Commission accepted, modified, or rationalized these distinctions.
This empirical approach helped the Commission resolve its practical problem by defining a list of relevant distinctions that, although of considerable length, was short enough to create a manageable set of guidelines. Existing categories are relatively broad and omit distinctions that some may believe important, yet they include most of the major distinctions that statutes and data suggest made a significant difference in sentencing decisions. Relevant distinctions not reflected in the guidelines probably will occur rarely and sentencing courts may take such unusual cases into account by departing from the guidelines.
The Commission’s empirical approach also helped resolve its philosophical dilemma. Those who adhere to a just deserts philosophy may concede that the lack of consensus might make it difficult to say exactly what punishment is deserved for a particular crime. Likewise, those who subscribe to a philosophy of crime control may acknowledge that the lack of sufficient data might make it difficult to determine exactly the punishment that will best prevent that crime. Both groups might therefore recognize the wisdom of looking to those distinctions that judges and legislators have, in fact, made over the course of time. These established distinctions are ones that the community believes, or has found over time, to be important from either a just deserts or crime control perspective.
The Commission did not simply copy estimates of pre-guidelines practice as revealed by the data, even though establishing offense values on this basis would help eliminate disparity because the data represent averages. Rather, it departed from the data at different points for various important reasons. Congressional statutes, for example, suggested or required departure, as in the case of the Anti-Drug Abuse Act of 1986 that imposed increased and mandatory minimum sentences. In addition, the data revealed inconsistencies in treatment, such as punishing economic crime less severely than other apparently equivalent behavior.
Despite these policy-oriented departures from pre-guidelines practice, the guidelines represent an approach that begins with, and builds upon, empirical data. The guidelines will not please those who wish the Commission to adopt a single philosophical theory and then work deductively to establish a simple and perfect set of categorizations and distinctions. The guidelines may prove acceptable, however, to those who seek more modest, incremental improvements in the status quo, who
