I can see you haven't grown past your modern American college miseducation. You need a little street education. My bet is you couldn't even survive ten minutes with your "proletarian" without catching you "lumpens"!
If you were "with the people" you wouldn't want the violent felons who victimized the "the people" back out on the street.
If society wants to hold prison officials responsible for prisoners brutalizing other prisoners, it better first return control of the prisons to those official!
The system IS "ill-designed and dysfunctional", but lawyers, courts, journalist and social activist have had more to do with creating that system than the prison officials.
I don't want predators on the street, ever.
The prison officials are part and parcel of the damage the lawyers, legislators, and social utopians have done and will continue to do.
Their work is not done - there's only 2,000,000 Americans in prison!
