5. A Concluding Note
The Commission emphasizes that it drafted the initial guidelines with considerable caution. It examined the many hundreds of criminal statutes in the United States Code. It began with those that were the basis for a significant number of prosecutions and sought to place them in a rational order. It developed additional distinctions relevant to the application of these provisions and it applied sentencing ranges to each resulting category. In doing so, it relied upon pre-guidelines sentencing practice as revealed by its own statistical analyses based on summary reports of some 40,000 convictions, a sample of 10,000 augmented presentence reports, the parole guidelines, and policy judgments.
The Commission recognizes that some will criticize this approach as overly cautious, as representing too little a departure from pre-guidelines sentencing practice. Yet, it will cure wide disparity. The Commission is a permanent body that can amend the guidelines each year. Although the data available to it, like all data, are imperfect, experience with the guidelines will lead to additional information and provide a firm empirical basis for consideration of revisions.
Finally, the guidelines will apply to more than 90 percent of all felony and Class A misdemeanor cases in the federal courts. Because of time constraints and the nonexistence of statistical information, some offenses that occur infrequently are not considered in the guidelines. Their exclusion does not reflect any judgment regarding their seriousness and they will be addressed as the Commission refines the guidelines over time.
