These people were going to be released shortly in anycase.
Criticise Labour all you like, i do! but this is one issue thats not on them, they had no choice.
Violence in prisons is rife, as is overcrowding, record numbers jammed into cells designed, by the Victorians, for 2 now have 4 inmates.
Not got a drug habit? go to prison, then you'll acquire one, which means when you are released, you'll commit more crime to feed that habit, wow what a ridiculous state of affairs!
If the streets aren't safe because of this release, thats down to the Tories not building enough prisons for their sentencing guidelines.
And yes, to the pp, Blair didn't build prisons either, prisoner welfare is never high on voters or governments agendas (unless it suits them to knock the other side, thats what is childish) but if you want safer streets, then prison and rehab are vital.
