Haven't watched it all because I was out last night, but unusually my husband was full of it when I got home. From what I have seen, yes I agree, they are disgusting, awful thugs.
Twenty years ago I worked as a care/day-care assistant in an NHS home for the same client group. I have to say that whilst I thought the powers-that-be were a little over-protective of the residents at times, I can honestly say that staff were never, for one moment, allowed to treat them like that. Some of our older residents had spent their childhoods in harsh, institutional regimes but I don't think they'd ever suffered anything like those poor folks at Winterbourne View.
