Report on a survey that the Center undertook at the request of the Committee on Criminal Law of the Judicial Conference of the United States of all district and circuit judges and chief probation officers regarding their experiences with and views of the Federal Sentencing Guidelines. Overall, responses did not reflect a groundswell of support for major overhaul of the Sentencing Guidelines. In general, chief probation officers were less supportive of change to the current guideline sentencing system than were judges.
