The Dutch anti Corona restrictions movement held a demonstration at Sunday 17th of January. Despite the Mayor of the city, Femke Halsema, laying restrictions rules upon the contesters. As the amount of participants 500 people, and the duration, and the location should have been changed according to her. This didn't happen because more than 10.000 participants were not on a demonstration, as they declared, they were there at their personal account and just having coffee in Amsterdam at a sunny Sunday afternoon. The riots broke loose after about 1 hour. The Dutch undercover police mixed with the protestors and began to make some riots. Pushing people, shouting, and lighting fireworks. Then came the water cannon-truck, and then the police horses and dogs. They had no problem hitting people on their heads. About 120 people got arrested.
