No no and no
You people have it all wrong I think - what we need to do is make PROFITABLE PRISONS. That way the inmates work like slaves all day long to compensate their victims and then base their "time" on reasonable amounts they owe. This would also considerably streamline sentencing.in all cases costs of incarceration should be borne by the convicts as well. On top of all of this once you've been breakin stones for the last 12 hours you might not feel so much like fuckin little Jimmy in the bunk next to you.
Basic guidelines might be:
Armed Robbery - Value of property stolen
Burglary - Full reimbursal of stolen and damaged property as a result of the burglary.
Drugs - Value of drugs consignment
dealing - Estimated value of earnings/profits
Rape - Estimated value of crime , say $100 (doubtful rape of a prostitute) to 10,000,000 (rape of a kid)
Murder - Spend rest of working lifetime paying off family
tax evasion - Amount owed
Car theft - Value of car.
Profit equals efficiency. People should be dying to build prisons.
