I just found more details on this story. Apparently, this woman has had conflicts with this hospital before, and the police were called on her many times.
Perhaps she’s not very polite. But, I know from personal experience that sometimes hospital staff doesn’t like when you speak up or refuse to follow along with everything - even when you do so politely but firmly - and they will punish you for that.
It’s possible that she was mentally ill. We’re going to know a lot more about this case, no doubt.
