This is an experiment that was conducted about the reporting of domestic abuse. It was conducted in South Africa, but I would suggest that the results in many countries would be more similar than we would like to think.
I had to watch it with the volume off because the sound of the assault was a bit too realistic for my liking.
In the video, neighbors come to the door right away to complain about the noise when someone is playing the drums. But nobody comes or calls the police when they believe that a woman is being abused.
I think every one of us should think about what we would do in such a situation, and if we ever find ourselves in a situation where we see or hear someone who might be in need of help, we should do something about it. Even if you aren't entirely sure whether they want help, I think that the consequences of not calling are far too real.
