There is a classic song, that I do not thing very much of, Ralph McTell, Streets of London: https://www.youtube.com/watch?v=DiWomXklfv8. Today though, the more relevant song would be the Knives of London, given the explosion of knife attacks and crime:

“Race-denialism is all over the Western world—the notion that race itself is a sort of optical illusion; that different races can, after a bit of social engineering, be brought to present the same statistical profiles on all traits; that when they present different profiles the only possible explanation is malice on the part of white people; these are the great dogmas of our age [Antiracism, Our Flawed New Religion, by John McWhorter, Daily Beast, March 14,2017 ] carved on stone slabs and worshipfully preserved in the temples of our culture. Here's a cute example: the epidemic of knife crime that has been plaguing Britain for several years past. Guns are hard to get in Britain (although not that hard). So the more commonplace types of lethal interpersonal violence—notably underclass gang warfare—are stabbings with knives. Where the soundtrack to a warm night in Chicago, Baltimore, or Detroit features gunshots, the corresponding audio for London, Birmingham, or Manchester is of metal blades penetrating human flesh.

This is quite a new thing. Yes, yes, I know about Jack the Ripper. Statistically, though—culturally—knife crime has not been a British thing. Growing up working-class British in the years before mass immigration, I absorbed the idea that fighting with knives was sneaky and unmanly. Knife crime was practised only by lurking weaselly types from the outer fringes of the civilized world. Englishmen fought with their fists, Irishmenwith the stout blackthorn, the Welsh and Scottish … I forget, but it wasn't knives.”
The mystery deepens about who exactly it is that is stabbing, slashing and chopping whoever with cold steel. Could it be the white nationalists up to their tricks again? Or could it be British supporters of Donald Trump, which is pretty much the same thing, only worse? Or is it just that being stabbed with a knife while out getting some fish and chips to tuck into, is just the way life is now in Britain? Diversity certainly is exciting, in a penetrating kind of way:
