AOG, I said he is, at the very least, in a supported living arrangement. Given what else was in the DT report, my guess, and it is just a guess, is that for him it means a home with other people where there are carers on hand all the time.
It is likely that he will have his own room or bedsit, and while nobody will plant anything in his bed or his room to spy on him 24/7, there are various devices available which allow staff at such places to monitor the residents for their own safety and comfort. I'm talking about things which can, for example, monitor bed wetting, monitor whether someone is in their bed (in case they have fallen out) or which can let staff know when the room door has been opened (in case someone goes wandering in the night, or in case someone who shouldn't goes into a room.
Now, that may sound rather Big Brother-ish but it isn't. The people concerned are vulnerable adults. They are not disabled enough to require 24/7 care, but they are not independent enough to live with minimal supervision in the community, so it all comes down to compromises ... using the tools which are available to ensure comfort and safety while still preserving a degree of privacy and independence.
