Yes, there really is a HMP Isis - or rather, more correctly, HMYOI Isis. It probably even also holds a few exploding jihadists who have failed to go off. It's very modern in a bleak, soulless, institutional way unrelieved even by the pastiche architectural quirks incorporated by HLM Architects. It's probably packed with well-meaning therapists, reading tutors, youth mentors and deradicalisation co-ordinators and the screws probably aren't called screws but Custody Service Operatives or something. I'll bet it's inclusion of heating and sanitation drives some of you to fury at such 'softness' and I'll bet it does absolutely no practical good at all except keeping a few score young crims off the streets for a while.
Until the fairly recent criminal justice reforms, Hollesley Bay Borstal on the Suffolk coast held many of the young men who will now find themselves on Thamesmead marshes. It was cold, crowded, insanitary and uncomfortable and the boys were housed in Victorian brick barrack blocks as cold as ice when the Siberian winds came tearing like knives over the North Sea. The boys worked an 1,800 acre farm and moreover did so with horses - Suffolk Punches. You could always tell the Borstal colony's farmland; it was the neatest, best managed, healthiest land you could see, with tidy well-layered hedges and gates with rectitude. They had no therapists at all, the screws were called screws and the County Council library van called once a week for those who could read. It successfully reformed thousands of boys, ensured the survival of the rare-breed Punches at a critical time and produced quality food for the market.
Still, you can't let effectiveness stand in the way of progress.
