Are the 305 million people living in the United States the most evil in the world? Is this the reason why the U.S., with 5 percent of the world’s population, has 25 percent of the world’s prisoners and an incarceration rate five times as high as the rest of the world?

Or is it a matter of a criminal justice system that has gone dramatically wrong, swamping the prison system with drug offenders?

That rhetorical question, asked on the floor of the U.S. Senate by Virginia Senator Jim Webb, fits into what looks like an accelerating shift in public sentiment on the way that a long parade of administrations has been dealing with illegal drugs.

Advocates of drug reform sensed a change in the public mood even before Webb, a Democrat who served as secretary of the Navy under Republican Ronald Reagan, introduced a bill last month to set up a blue-ribbon commission of “the greatest minds” in the country to review the criminal justice system and recommend reforms within 18 months.
