The authorities should do something. Don’t get me wrong I am all for free speech and the right to protest, and obviously not everyone involved here is a militant but clearly some are. They are intent on trouble and they need to be dealt with. No-one wants to see marches or protests banned but clearly it will be inflammatory and intimidating to the ordinary players and the businesses around the protest. Inevitably they will get caught up and be unable to go about their lawful business. Banning the march ensures our spaces are clear of hate speech, ensures brand safety.
