I would imagine one of the reasons these people end up sitting in jail is they do not have the money for a real lawyer and end up with a public defender. I am quite sure if they ever do commit a crime and get caught in the future they will have a nice settlement from the state to pay for their lawyer. Eventually it becomes a point to keep these people in jail because the government screwed up. releasing them admits to liability and that will be turned into a lawsuit by a lawyer working for a cut. In the end it is a huge waste of our tax money to have done this. first you consider years of imprisonment and the costs of that, and now we get to pay for the mistakes of the government.
i would also like to point out that the people mentioned have been in jail for long periods of time and many were not placed there by the Obama administration. The laws that allow this, and the policies that make it happen seem to have been made pre-obama so blaming him and holder for causing this is not proper. I don't know who made this policy, but blaming Obama and co. for not checking out every single federal inmate is a little much considering how many of them there are, and the mountains of case records there are.
Think if Trump get elected how much resistance he will face with in all phases of our country from people to military to politicians. He must not win.
