Mark Duggan. A revolting little gangster killed in an entirely justifiable shooting. Thing about 2011, though, was that it wasn't explicitly racial in nature. There were as many white toerags as black toerags looting and burning.
And yes, it's weird just how gentrified Herne Hill and Brixton are now. Our main office is in HH now and the area is very nice indeed.
Needless to say, Thornton Heath has somehow resisted gentrification.
