for most ordinary people it is the risk of being caught and labelled a criminal that is the major deterrent, not the length of the sentence.
maybe social pressures just don't work on them,
Here lies the root of our disagreement, we came from the different sides of town.
I come from the sort of area where a criminal record was nothing to be ashamed of, quite the contrary in fact. Also it was often acquired long before the consequences could be understood, if the consequences could ever be understood because it was only a barrier to a lifestyle which they were
never going to get anyway!
The other option was the Army and criminal conviction was not a barrier back then.
When my friends came to the pub from Court, not only did they take off the suit but also the pack of lies that were part of the court game. The two important questions before going were "Will I get time" and "how much". If they didnt or it was short, then they were laughing at the Judges.
Another point that is denied by those not actually at the receiving end of the Justice system is just how arbitrary it all is, the main reason why people "re-offend" is because they are on the Police lists and so much easier to catch and convict. I know plenty who have been convicted for crimes they didnt commit after release (though that doesnt mean they hadnt done other things
), I know far, far more who were not convicted for crimes that they did commit.
