of course with an increasing population you are going to have more people in jail, there will be a direct correlation which is not linked to sentencing.
but i dont think your source backs you up, infact i think it contradicts your point entirely, thanks for providing it: i take it you understand the difference between a custodial sentence and a suspended sentence?
ther are no where near the same, one is an utter let off.
lets see:
this chart shows me a consistent drop in custodial sentences until 2007 and then a slight rise but still well off where it was in the booming late ninties/2000's?
you can see how the judges are passing out hugely grossly underwhelming sentences by their decision to have a boom of suspended sentences. how you can count that as a total custody increase i am not sure.
in this next exerpt you can see how the magistrates have clearly been pressurised into reducing the number of immediate custodial sentences;
you see how all the 'percentage' changes are down? that means less people going to prison in 2008 over 2007 from the magistrates.
You don't need to do that, you just need to get a setup that isn't adversely impacted by public opinion... Say a system of clear laws, sentencing guidelines, and someone who will apply them impartially?
but who sets the sentence guideline impartially? do you think that ANY human being is actually completely 100% objective and not subjective? personally i dont think that you can be. peoples values, upbringing etc will largely influence someones decision at any one moment in time as to what is a just or fair sentence for crime X Y or Z. at elast if the majority agree to it then there was a majority consent, rather than the personal expression of an individual which you seem to be advocating.
We imprison more people than we ever have, and crime continues to get worse. Does this not say something?
it says we need more prisons. CUrrent rehabilitation methods do not suceed, but then we do not know any others that DO work. in that case you must do what is right for the majority to protect them, rather than protect the offender.
Because it automatically assumes that the option with the highest popularity is the correct one, which is a fallacy.
in your insular; 'there must be someone who knows better than the people' viewpoint maybe. but as i said, the person who sets them is bound by their own morals and personal beliefs. who gets to choose who this rule/sentence setter is? the majority, or the elite who will advocate rules, policies or people who are like them, think like them and are indeed one of them.
and ultimately who is that person accountable to?
i think you have to forget the notion of prison as a chance to create better people. the reason for a prison is because someone has done something which has been deemed unsocial, and infact that unsociable that they need to be punished and locked away from society in the hope that the experience of being without the luxury and frivalities of society that they want to become a 'better' civillian to avoid going back. this is obviously not the case.
