THE LIBERATION OF CANARY WHARF from the human beings who brought you EVERYTHING IS OKAY. There's a joke here via the late and great Bill Hicks, the "ID - I'm me, you're you, he's him" joke... didn't work with these fake-police-officers either.
Technically, though Everything Is Okay's right, the authorities are always going to easily (and legally) pull the 'breech of peace' by-law on these sorts of Freedom Positive individuals. That's the way society is - we accept arbitrary laws for the supposed good of the majority. It's a nice (if naive) attempt to WAKE PEOPLE UP. Grass roots effective, let's say.
