From the Sentencing Project out of Washington DC. If you think about the cost of paying for all these individuals, it puts a whole new light on the issue. Here is the blurb from the Sentencing Project:
The United States is the world's leader in incarceration with 2.2 million people currently in the nation's prisons or jails -- a 500% increase over the past thirty years. These trends have resulted in prison overcrowding and state governments being overwhelmed by the burden of funding a rapidly expanding penal system, despite increasing evidence that large-scale incarceration is not the most effective means of achieving public safety.
50,604 of those incarcerated were from Ohio in 2013.
