Alleged context (feel free to correct if you have info in comments):
After Israeli Maccabi hooligans terrorized Amsterdam, the Dutch government demonized the pro-Palestine movement and banned protests. People came to protest anyways (peacefully)
The police arrested peaceful protesters and put them in a bus. They were driven to a parking lot. The police released them from the bus in a parking lot near a station.
While the protesters were walking to the station the police started hitting them. Allegedly for not moving fast enough.
The job of the police is to enforce law and government decree without violence. Violence is just a tool they have access to, but it doesn’t mean it should be used for every kid and granny.
