In early November, the Bureau of Prisons (BOP) is scheduled to release approximately 6,000 federal inmates convicted
of drug trafficking offenses. While some have cheered the releases as a sign of efforts to "right size" drug sentences or
reduce mass incarceration, others are concerned about what effect it might have on public safety.
Why Are These Inmates to be Released Early?
In April 2014, the U.S. Sentencing Commission (Commission) submitted to Congress proposed amendments to the
Federal Sentencing Guidelines (Guidelines) that would reduce by two levels the base offense levels assigned to drug
offenses, thereby lowering the Guideline ranges for most federal drug trafficking offenses. In July 2014, the
Commission voted to apply the amendment retroactively (with the condition that no prisoners who receive reduced
drug sentences may be released before November 1, 2015). The amendment went into effect on November 1, 2014, in
the absence of disapproval by an act of Congress.
How Do the Guidelines Function?
Congress establishes the maximum penalty, and sometimes a minimum penalty, for every federal crime. The Guidelines
assist federal courts in determining an appropriate imprisonment term and criminal fine for a particular offender by
providing a recommended range of sentences that fall between the statutory maximum and minimum penalties. The
Guidelines assign drug trafficking offenses to 17 "base offense levels" corresponding to the kind and amount of
controlled substances involved in the offense. In calculating an offender's sentence, a court starts at the offense level
recommended by the Guidelines and then increases or decreases that level depending on aggravating and mitigating
circumstances. The final offense level, in combination with the defendant's criminal record, is used to determine the
offender's sentencing range.
The Commission—an independent judicial branch agency responsible for issuing, and periodically revising, the
Guidelines—must follow several statutory directives, including ensuring that the Guidelines reduce unwarranted
sentence disparities and minimize the likelihood of overcrowding in federal prisons. The Commission also has


discretionary authority to make Guidelines amendments retroactive. However, no one is automatically entitled to a
sentence reduction by virtue of a retroactively applied Guideline amendment; a court must first determine (1) the
prisoner's eligibility for a reduction; (2) if such reduction is warranted, after considering several statutory factors
(including the risk to public safety and the defendant's criminal history and behavior in prison); and (3) the extent of
any reduction.
What Effect Might This Have on the Federal Prison Population?
The Commission's changes to the Guidelines were motivated, in part, by overcrowding in federal prisons. The number
of federal inmates steadily increased from 24,363 in 1980 to 210,567 in 2014 (30% over rated capacity). The number of
prisoners decreased in both 2013 and 2014 because in both years releases exceeded admissions (see Figure 1). The
recent decrease in the federal prison population was mostly the result of fewer offenders entering prison rather than an
increase in the number of inmates being released.

About half of federal inmates are drug offenders, and nearly all (99%) drug offenders were sentenced for trafficking
offenses. Approximately three-quarters of drug trafficking offenders are serving sentences of five years or more (see
Figure 2).

Notes: Data are for BOP inmates at the end of 2012, the most recent data
available.
It is estimated that between 40,000 and 45,000 are eligible to apply for a sentence reduction. Inmates who have been
granted a sentence reduction have, on average, had their sentences shortened by 23 months, from 131 months to 109
months. Given that drug offenders are still facing, on average, nine years' incarceration after receiving a sentence
reduction, changes to the Guidelines might only have a modest effect on the size of the federal prison population. Also,
the effect might be limited by the fact that inmates sentenced to a mandatory minimum term of imprisonment, as well
as those sentenced as Career Offenders or Armed Career Criminals, are ineligible for a sentence reduction.
Current Legislative Efforts
Legislation in the current Congress would make offenders convicted for some drug trafficking offenses that carry a
mandatory minimum sentence eligible for a sentence reduction. Both S. 2123 and H.R. 3713 would reduce mandatory
minimum sentences for certain drug trafficking offenses. The legislation would also authorize retroactive application of
the amended mandatory minimums, permitting federal courts to reduce the terms of imprisonment of defendants who
were convicted and sentenced before the date of enactment. However, before granting a sentence reduction, courts
would have to consider several statutory sentencing factors, including "the nature and seriousness of the danger to any
person or the community," and the defendant's post-sentence conduct. (H.R. 3713 would prohibit a sentencing court
from granting a sentence reduction to a defendant with a prior conviction for a serious violent felony.)
Concerns About Recidivism
The release of a large cohort of inmates has generated concern about a threat to public safety. Data show that
approximately three-quarters of federal drug offenders released in 2005 were rearrested within five years. Drug
offenders were more likely to be rearrested for a public order offense (56.1%) or another drug crime (51.2%) rather
than a violent (24.8%) or property (33.1%) offense.
However, the inmates now scheduled to be released might not be at a greater risk to recidivate than other drug
offenders. As mentioned above, courts had to consider the offender's risk to public safety when making a decision about
whether to grant a sentence reduction. In 2007 the Commission adjusted the Guidelines to reduce disparities in crack
and powder cocaine sentences. The adjustment allowed approximately 16,000 prisoners to have their sentences
reduced. A subsequent analysis found inmates granted early release did not recidivate at a significantly higher rate.
Also, these inmates are to first be placed in Residential Reentry Centers and/or home confinement, and afterwards they

are to serve a period of supervised release.
