Police will be contacted in other such situations - families who complain about a parent's mistreatment in a care home, for instance. Or there's Graham and Anne Dixon, who complained to the NHS hospital about their child's death, and she got imprisoned and strip searched by Hertfordshire police. State organisations do stick together, in particular with local authorities - they're mates, essentially.
I had the police called out on me by Barchester's Reigate Beaumont - when I was visiting my mother on Christmas Day, no less! Oh, I wasn't arrested, I had a friendly chat with the officer and explained what the care home was like and why we'd fallen out. But I later discovrered via a Subject Access Request to the Council - who took nearly half a year to respond, not the 40-calender days - that Surrey's Adult Safeguarding teams aka social services - had tipped off the care home to do it, and it was after a) I'd reported a different care home, Firtree House Nursing Home, also in Reigate and Banstead, to the local press and b) I'd raised concerns about my mother's low fluid intake at the new care home, little suspecting she'd been placed on proactive end-of-life care, saying 'people are going to hear about this, y'know..' They thought I'd take it to the press.
Nothing came of the police chat, but we moved Mum out of the care home in the New Year - nonetheless it allows the authorities to misleading write on your parent's notes that they 'had to call the police out' which most will interpret meanly, given that they themselves have never had that happen to them. What's more, I suspect that if I sent a Subject Access Request to Surrey Police, their account of our meeting may be very different - and unfavourable - to how it actually went.
'Confiscating devices' I take to mean, 'we can shut down your basis of operations and also trawl them for evidence of something actually illegal we can hit you with - cocaine use, or such like.'
