This won't make me popular here, but:
On the one hand, you can kind of see why this is happening.
People, if they are lucky (yes, lucky.) enough to have a job take home about 9,000 a year. Houses cost a million each. You'll pay 2 hundred thousand for a broom cupboard in the middle of a post-industrial wasteland in London. That is the real mathematics of civil unrest. And we have a conservative government who couldn't care less and is busily sending the message, via cuts, that 'oh no, we couldn't care less about you, we'd rather give our money to the bankers'.
On the other, the only shop to escape looting was waterstones. And somebody, unaccountably, stole a load of imodium from boots. What does that tell you. Idiots? They couldn't even spell 'moron'. Most of this is opportunistic criminality, and the sooner we clean the streets of these cretins the better.
