If that's a nerd where you come from, you have my sympathy.
The rioters are w*nkers who are looting as an excuse for lacking respect for humanity. Damage has been estimated at something over £200 million. There were 16,000 police on London streets a couple of nights ago, which took them away from other major cities, which prompted looters elsewhere. There has been another event in the last day which was the EDL (a racist/nationalist far-right group) kicking off on the tail of everything else. In Brimingham, between 1500 and 2000 Sikhs lined the streets to protect local homes and businesses, and several of them carried swords - funnily enough, there was no trouble. What sparked that was the murder of three young lads out looking after their property - they were driven over on the pavement. There was the incident with the Malaysian student injured and being mugged by those pretending to help him. There have been several deaths and severe injury, and people have lost their homes in arson attacks, as well as many small businesses effectively finished from the damage. The original event that sparked a peaceful protest somehow escalated and nobody's quite sure why, though there are a few theories. Everyone I speak to has been a bit dumbstruck by it though, it just happened.
The police were instructed at first to just stand by and watch, not to intervene, as they had previously been criticised for heavy-handed tactics and causing the death of innocent bystanders. But inaction has backfired too. So it's all a mess.
Putting some perspective on it, someone I know said that in the Middle East, they riot to overthrow dictators - here it's an excuse for nicking stuff.
