Wow. Very nice work.
Particularly interesting are your points about being punished (kept in prison longer, less favourable parole conditions etc.) for your circumstances and the actions of others.
On the one hand, yes, statistically these factors do increase the likelihood that you will re-offend. On the other hand, this kind of practice violates a basic principle of justice.
Ultimately, this is the problem with any kind of statistical profiling. Statistical profiling is inherently unjust (even if, pragmatically speaking it is extremely useful).
