Perhaps. On the other hand, she played a role in escalating the situation. It took a doctor stepping in to find out why the woman was being held upside down.
Context should be an important factor when deciding to intervene and how to intervene. If I encountered such a situation in a hospital, I would have interpreted it as unusual and beyond my comprehension, but it would not have struck me as an intent to cause harm. People tend to go to a hospital for help. Those who hurt others in a hospital would likely do so through violence.
I'm not suggesting that she should not have intervened, but she (and the security guard) should have understood the situation first.
You have read the title and know the woman is not being harmed. You probably don't have to deal on a daily basis with drugged and mentally unstable people, unlike someone who works in an emergency room.

I don't live in an area with any BLM protests. Instead our boring town has started to freak out about mythical child nappers. Cars have been searched and people have been beaten up by there over reactive types. Different politics, same attitudes.
