Someone in the comments in the National helpfully posted a link to the debate in Hansard and Ann Widdecombe's contributions

But, as we're seeing regarding SSS, in some instances prisons and hospitals seem to feel they're able to decide what laws and guidelines they follow and which they don't.
Regarding Heather Herbert's comments, if he'd posted he didn't like her, he was glad she was dead, that she was a bigot, that's unpleasant but fair enough. The specificity of 'screaming in agony', is nauseating and far too close to the bone when so many women experience just that at the hands of men. Whether they survive it or, as appears with Ann, it results in their death.
I hope he never experiences anything like that. I won't even wish infection on him. As to whether or not he keeps his job, that's up to the university.
