There are now more Americans in jail -- 6 million -- than there were in Stalin's Gulag, reports Fareed Zakaria, in a column called "Incarceration Nation."
And it's not just a relative population thing.
The U.S. has 760 prisoners per 100,000 citizens.
What's to blame?
The "War on Drugs."
More than half of America's 6 million prisoners are in jail for drug convictions, with 80% of those in jail for "possession."
