Many moons ago i did a quick check of some miscreants record (kindly reproduced in the paper).best bit of rehab tried out anywhere was the three strikes system in some states of the USA, concentrated their minds not to get caught more than once but if they were stupid enough to continue offending they were stuck somewhere safe for the public at large, i believe it did wonders for crime rates in new york
IIRC he'd been convicted of 26 crimes for which he'd been given sentences ranging between 6 months and 5 years, he was barely in his late 20's and his sentences had obviously been cut short or served concurrently.
One. I'd ban concurrent sentencing. It makes no sense. one day is worth one day.
Two. Introduce a system where for each conviction you get a multiplier. ie x1 on first conviction. x2 on second, x3 and so on.
Three. Introduce a system where any time cut on the previous sentence is suspended and reimposed on conviction for next offence.
So. Imagine a miscreant. Commits an offence and gets 12 months. They are let out at 6 for good behavior. Commits a second offence. They are returned to nick and and commence the six months that they were let off. And then start their second sentence (lets say another 12monther) but, and here's the kicker, it's now 24 months as it is there second offence, for parole purposes it counts as a 24 month sentence.
I think I worked out a system like that would have meant the prat mentioned above would have been dead long before his 13th conviction was served.
