Eric Holder, the Attorney General, has made it a priority to reduce overly-long sentences and unjustifiably high incarceration. He attributes this decrease to,
. . . . efforts to reduce long mandatory minimum sentences for nonviolent offenders. It also comes four years after the passage of the Fair Sentencing Act, which shrunk the disparity in sentences for crack and powder cocaine . . . .from the Wall Street Journal.
This coincides with a drop in the overall crime rate. The correlation, or disconnect, between the drop in crime rate and decease in prison population is an interesting one, and can add to the ever-growing arsenal against the general deterrence theory.
