Not easy to enforce. Like, the political'show' on Reumanplatz in Vienna was a farce. Hours later there was a knife fight in front of Tichy's Ice Salon.
About this story: The police is too busy pinning a right-wing radical to the ground, while other police, according to some posts on X, were running away, blond ponytails bobbing. The policeman that got murdered acted in response to their given mandate by their Interior Ministry, to arrest those 'evil anti-islamist right wing radicals'. A wrong reaction cost him his life!
Good thing one of the male police officers stayed and shot the knife man.
And yes, I've seen pertinent videos posted before they were deleted/banned.
