It would be interesting to see the re-incarceration rate of those set free from charges like that.
I wonder if jail time has the opposite effect of rehabilitation for many, especially considering how much harder life can be with jail time on your record, or even just the black hole in your resume that you have to explain.
Not to mention that you spent the last however many years being told and treated like criminal scum, I imagine that would have a fairly significant impact on your mental health and self image, as well as your relationships with friends and family.
