I dunno. I think it might be interesting to get this cleared up.
He had his own accommodation there. I wouldn\’t be at all surprised to be told that he had the keys to that.
He might have had the keys to get from the boundary to that accommodation. Wouldn\’t worry me if he did. Through the Judas Gate and down to his bedsit. Shrug.
The way what we\’re being told reads it is that he had the keys to the high security wards. Something I would be worried about and something that I think is extremely unlikely.
But wouldn\’t it be useful to know which of the three really happened?
