What we know: Without a functional reintegration program, convicted criminals are extremely likely to end up back in the "system." The definition of insanity is doing the same thing over and over again, expecting a different result. We have the largest, almost 1/4 of the world's, prison population on earth -- with our total population comprising only about 4% of the world's total. Something has to change. Functional reintegration may work to break this cycle. It's fiscally responsible. It's also just plain humane.
