Extract from the article:

“Female protesters have been at the forefront of escalating protests in Iran and have been burning headscarves, after the death in custody of a woman detained for breaking hijab laws…

Ms Amini was arrested in the capital last week by Iran’s morality police, accused of breaking the law requiring women to cover their hair with a hijab, or headscarf, and their arms and legs with loose clothing.” https://www.bbc.com/news/world-middle-east-62967381

The “so little knowledge” in this specific example could be the knowledge of one single incident. Of course this is not an isolated incident but it seems like knowledge of this one event has the potential to spark massive change in Iran.
