Many commentators on LBC including Rachel Johnson are expressing dismay at how the police have handled Republic's pre-arranged peaceful protest in particular. They have never had a better recruiting sergeant for the cause. Indeed, their twitter followers have put on 35k and donations have increased 15k since the events of yesterday, and they have got the message out to 100s of thousands of more people and the news of their heavy-handed treatment have gone around the world.
Since as monarchists never tire of telling us they are an essential part of the British constitution and are paid literally royally for that job then the right to peaceful protest which was agreed in advance is a democratic right to be cherished and supported whatever your view.
Yesterday was a watershed moment on the long march to a Republic - helped in great measure by the actions of the Police, and for that we must be grateful.
