Nora Callahan, writing for Narco News, presents a layman's view of Booker as it pertains to drug sentences and says that most drug offenders will be left behind:

According to the Supreme Court, the new ruling can only be applied from this day forth, aside from prisoners still on direct appeal, and brings us to the 'left-behind.'.... today, in a federal prison near you, there are old-law prisoners (sentenced before 1984), and old, new-law prisoners (people sentenced between 1984-2004 approximate), and brand new, new-law prisoners (after 2004 - post Booker).

The 'left behind' in this series isn't best selling Christian fiction, but real people, imprisoned unfairly via US Sentencing Guidelines pre-Booker case. Most in federal prison will not experience any rapture with the notion there is a fissure in the cracks of the foundation of the war on drugs. They want to come home. Many feel personally responsible for the new movement to end injustice, but most will gain no reward for their hard work.

It really is unconscionable that Booker is not retroactive. [Via Libby at Last One Speaks.]
