Theres no punishment for antisocial behaviour or indeed for most things so its hardly surprising that they carry on the way they do. They avoid the consequences of their actions. Regarding the poetry I'm not a great fan of poetry anyway but its not very good in my opinion.
I think the soft touch (They are touched!) brigade have had plenty of chances to prove to us that their methods fail every time. Time to get tough again, harsh regimes and not for a short period of time either. Two years without the trimmings ie no tv, no computers etc. Just a bed and a sparse cell, keep them physically occupied between 6 am and 8 am, breakfast, school with old style teachers. At 4 pm more physical work then at 8 pm lock them in their cell for the night with 4 to a cell. 3 basic meals per day, no remission and only in their last month start the transgression back into normal life on the outside. Repeat offenders have their sentences increased by a year at a time.
