A few points. It's a breach of facility security for cellphones to be used by inmates. In the state where I reside, it's a felony to have a cell phone, as well as to aid and abet such a security breach. News outlets that retweet posts from inmates with illegal cell phones are liable to criminal charges of aiding and abetting, or similar charges. IANAL, but this is my (sketchy) understanding of the circumstances regarding communications undertaken illegally from within a prison. I have no idea of UK law, but do not doubt similar laws apply in Belmarsh.

Canteen is a privilege, and not considered a necessary means of sustenance. Any charge that prison food is not completely safe and nominal for sustenance is going to be met with every scrap of legal power Belmarsh, and the UK, can muster. The fact is that prison food is not safe, it's often procured via criminal corruption, and I have personally witnessed prison administrators stealing good food from inmates, and food (particularly meat) marked 'Not for Human Consumption' served to captives. It is impossible to overestimate the degree and depth of corruption in prisons. The food is not safe.

It is also very likely that JA is being medically tortured. Medical staff normally torture inmates, withholding necessary medications sometimes until surgical intervention is necessary to save their lives, if not all their parts. I have seen it. JA is a high value detainee in the eyes of the CIA, and they commonly resort to torture. It is their joie de vivre. They live for it. I have no doubt JA is being fed horrible psychoactive chemicals that are deranging him.

He is not safe, and 4 months is forever. Prison is a place where the minutes drag on forever, and the years disappear. The corrupt criminals that run such places could kill him tomorrow, or the day after, with zero consequences. They believe they are completely immune from legal sanction, and they're mostly right.

Thanks!
