Any society, every society of 58 million, contains within it a few tens of thousands to hundreds of thousands who will happily riot given half a chance.
You can call them feral rats if you like, chavs, the lumpenproletariat, whatever, but they’re always there.
It’s the “half a chance” which changes. As with everything else technology changes and so will those tactics which will succeed or not. The Blackberry messaging service, Twitter, whatever, gave that half a chance to those who would happily riot.
Four days later the police had worked out how to counter that new technology.
Meh, it’s over now until another technological shift.
