a. Less than 10% of us prisoners are in private prisons, its really a red herring when it comes to talking about problems with the US justice and penal system. Its also a trailing indicator, private prisons started expanding after the US started passing a bunch of tough on crime rates. I also can't help but notice that the folks who complain about private prisons, never seem to complain about prison guard unions, who tend to lobby for the same sorts of laws as private prison companies, except, the also lobby for banning private prisons.
But, that's all a side track.
As anyone actually proposed anything useful in this thread? What should the US do regarding the border and immigration? Personally, I think we should copy Canada with our immigration policy and start actually controlling our border.
