The worst protest in the world?

I only ask since I couldn't see any of their placards clearly as the writing was too small, too thin, not contrasting with the background enough and almost invisible.... In fact the only word I could read, even when zoomed in, was STOP!

This was very much an impromptu Blip as I had planned something else which wll probably be blipped in the future whereas you don't see many useless Demos; especially not in Cambridge.
