Gosh, yes, Pain, I just found that Royal Holloway Tweet.
I think Aberdeen and Bath occupiers have had similar poor treatment.
At some point early in the occupation my daughter was part of, security decided to lock a fire escape door from the outside, to stop more students getting in to occupy the Senate House. At around the same time, the occupying students were having to pee in bottles as they weren't allowed access to the bathrooms. Also, they were not allowed to be given food. And the Registrar had the cheek to accuse the rallying students of bullying and intimidation! Anyhow, it was resolved satisfactorily after negotiation and publicity (thank God for SM!) and the students carried on for 11 days (with swapping out) until they achieved what they had been asking for, from what I had understood to be is one of the more hard-line university managements, though Royal Holloway is looking very hard-line at this point. I heard nothing about medication not being allowed in, and it seemed that on my daughter's campus, at least, there was, eventually, a good rapport between the student occupiers and the security staff.
To be honest, I think the holding of a silent sit in by supportive students in a central university building on an open day for offer holders, was what clinched the turnaround at my daughter's university. I don't know whose genius idea it was, but it worked!
I'm sorry for this digression from Trump.
