It might be good for the un-initiated but for me a lot of it is spent bigging the place up. Belmarsh is not the only place that has an HSU, there was one at Full Sutton, I was SSU trained, and there are others. They may not be operating currently but they do exist. Also Full Sutton and others took any prisoner whatever their category or escape risk and, again, Full Sutton has an unused old segregation unit that used to be opened and staffed when the situation called for it, I know as I manned it and flattened a con that was flinging food all over officers at the hotplate. We also had at least one inmate that self identified as female, and that was in about 96/97. I've also had to be on shift in the hospital wing a number of times, primarily for wing staff protection but also to watch a very large con who was completely Ga Ga, droolingly so, due to excessive drug use, I have no idea if he ever recovered.This 2 part series about Belmarsh (Hellmarsh, the inmates call it) is quite good. Gives a decent insight into what PO’s have to deal with.
One thing I would say is the place does look a lot more violent than what Full Sutton used to be, I wonder how much that is down to the Regime and calibre of staff though.
