In all fairness to the FBI, it's not easy for the US to maintain the highest documented incarceration rate in the world. I mean, shit, you try keeping 2 million (or roughly 700/100,000) people locked up without fomenting a revolution. It ain't easy, bro. Now, compound that problem with increasing proportional taxpayer costs for prisoners while simultaneously privatizing profits from the criminal justice system and you can see why the US can't be super-picky about who it convicts or on what evidence. I mean, c'mon: do you want justice or money?
