Decrease mandatory sentences for nonviolent drug offenses by people with limited prior records. Some 5,800 current prisoners who were convicted under guidelines that treated crack differently from powder cocaine could also get shorter sentences.
Expand drug treatment, education and job training, granting early release to many who complete the programs.
Limit the time juveniles in federal prisons can spend in solitary confinement.
This appears in the December 28, 2015 issue of TIME.
