The way I see it, what's happening is not an accident, but a normalization. The default norm of governance in the UK is that of a ruling class and peasants. It hasn't changed through time, only changed expression. One has only to read Charles Dickens to see how it is when the British empire is at its peak. The exception was the material wealth authorized to the peasants during the second half of last's century to serve as PR to the elites' values. What are these values? "There is no such a thing as a society" means that there is no such a thing as a British people. Hyper individualism and "the winner takes it all" culture means that the elite are not obliged to seek the well being of a society that doesn't exist. It's been remarked that the victims of the gangs are very often from the working class, which after financialization (post industrial capitalism) are a class of undesirable anyways. Sexual promiscuity is another "value" where women are advertised as cheap objects, especially in the movie industry (the mailman goes into a house, blahblah). After all, under the materialist paradigm, individuals are objects, and the non-existing society is just a bunch of separate objects.
The great reset and the "you'll own nothing and be happy" agenda didn't die, but people are quick to forget and be distracted by symptoms instead of looking at the causes.
People voted for brexit for more centralized control of the borders and that's exactly what they got, more control of the borders with explicit selection of incomers according to their criminal records.
I visited a "third world country" recently and noticed that the streets were calm and secure. Children play outside and women are not bothered. I asked about criminals and delinquents and several responses were along the line of "europe took them all". I was told twenty years ago when I was refused the renewal of my visa in a european country that it would be easier if I had a criminal record and a story of drug use, but since then I encountered several people with similar stories. In the 90's we used to joke that if you wanted a visa for the UK, you needed to join a salafist group (it wasn't really a joke). The members of these gangs in the UK would be killed in their countries of origin, but they are compatible with the elites' values and agenda.
So all these pseudo-"riots', as long as they are directed towards symptoms instead of confronting the roots of the causes, in the end they will not achieve much.
