Via Dana, this report.
The scariest paragraph that puts it in perspective:
The report said the United States incarcerates more people than any other nation, far ahead of more populous China with 1.5 million people behind bars. It said the U.S. also is the leader in inmates per capita (750 per 100,000 people), ahead of Russia (628 per 100,000) and other former Soviet bloc nations which round out the Top 10.The U.S. also is among the world leaders in capital punishment. According to Amnesty International, its 53 executions in 2006 were exceeded only by China, Iran, Pakistan, Iraq and Sudan.
Tough on crime indeed. So tough that they have to put more people behind bars every year. I think its a fair conclusion that tougher punishment ain't providing the necessary incentive for citizens to be law abiding.
