Six thousand drug offenders are being released from federal custody today and Monday. Nearly a third will be turned over to immigration and likely deported. Most of the rest are already out of prison, in halfway houses or home confinement, and will now be released to a probation officer. This particular release stems from a decision by the U.S. Sentencing Commission two years ago to cut sentences for drug offenders by two years on average. What does the future hold for those released under it and what does this mean for the efforts to reduce our prison populations?
