I think things happen but we don't hear about them as the prison keeps it very hush hush so that they don't look like they've failed in their duty to protect, they don't want any bad press. I actually remember reading somewhere that Aaron had been punched or something similar whilst in there, it was in some sort of small Glasgow paper or zine that you need a subscription to. Someone online was talking about it being in there. I never actually saw it though because you needed to subscribe to buy them. Can't remember what it was now. It could be wrong of course, but yeah..
