When a 26-year-old man became the first fatality of the riots yesterday, dying in hospital after he was shot in a car in Croydon the night before, it was a sad testament to the violence at the heart of the riots that have swept across London.
But the incident also highlighted a deeper problem: the gang culture that suffuses the capital and seems to be a factor in the ongoing anarchy.
The man had been shot after he and a group of friends had got into a row with another group, an altercation that ended in a car chase and the shooting. That incident appeared to have been the result of a long-standing rivalry.
The complexity of London's gang culture was further revealed by reports that warped appeals for gang unity had been taking effect, with hastily made alliances between the criminal groupings said to have been set up before Tuesday's looting in Clapham. One constant throughout was surely hatred of the police. On one British "urban video" website, gang sympathisers gathered to discuss the burning and looting that had taken place in Tottenham on Sunday.
Some voiced concern that the gangs were not sufficiently co-ordinated in their attacks on police: "I would love it if every click [clique] from north, south, east turned on feds am telling you a lot of fed man will quit their job. This should be the new wave f*** this click on click beef its (sic) pointless."
