Ex FH Pat, that gang will not be deterred by prison - half their mates are already inside no doubt. And their family.
The ones not already dead.

Statistically those with a good education are not going to prison - maybe they are not getting caught, but just maybe they find better ways to make money.
As prison is very expensive, the thinking is to pile resources into education instead. Give them a genuine stake in society and the real hope that they may have a nice home one day. Radical stuff eh?
