'Something out of a police state,' say demonstrators against King Charles' crowning.

London’s Metropolitan Police made 52 arrests during the coronation of King Charles III on Saturday, as the force faces growing scrutiny over its attitude toward anti-monarchy demonstrators. Republic, Britain’s largest anti-monarchy group, told CNN that police stopped six of its organizers and told them they were detaining and searching them. Graham Smith, the chief executive of Republic, was among those detained. When the organizers asked police why they were being detained, they were told officers “would figure it out” after they had searched the anti-monarchy protesters. After searching them, police told the six organizers they were arresting them and seizing hundreds of their placards carrying the slogan “Not My King.” The group posted on Twitter Saturday, commenting on “So much for the right to peaceful protest.” Members of environmental activist group Just Stop Oil also appeared to have been arrested on The Mall outside Buckingham Palace, the UK’s PA Media news agency reported.
