The UK classifies basic tableware as deadly weapons
My poor mom suffered from significant dementia in the year before she passed. Not long after I moved my folks into an assisted living facility, she contracted an infection that made her delirious, and she was reportedly ranting that she was going to find a knife and cut the bad pills from the doctor out of her stomach. The staff got my dad out of there and called me.
Other than hearing my mom come to the door and throw the deadbolt (as if that would keep the staff from just unlocking it?) I heard nothing, but the staff called the police per their protocol.
I was standing at the door when the cops arrived--two big guys, fully armed, in bullet proof vests--and they got the story from me and the staff. They then said "Whoa, whoa, wait, she has KNIVES in there?" to which I replied "Every one of these units has a little kitchenette, of COURSE she has table knives in there!" They started hemming and hawing about what to do, so I just said "OK fine, I'm going in and you cover me" and told the aide to unlock the deadbolt.
My mom was asleep in her recliner and we had to wake her up when the EMT squad got there. She had absolutely no concept of what she'd said earlier.
