I think the rest of the UK is looking on with bemusement. OK the family were upset at the shooting but as far as I am aware, the man in question was armed. It is pretty likely that he was involved in criminal activity or gang violence. The IPCC, the independent police complaints body is to investigate, as is required in all such cases and most reasonable people would expect such an investigation to take time. They were never going to get answers the day after the shooting. Then what happens, groups of thugs, some as young a 10 I believe, decide to wreck their own high street and pinch everything in sight. Now areas of London completely detached from the incident are hit by hooligans after expensive hoodies and trainers.
In the 80's, the riots in Toxteth, Brixton, etc, were the result of long standing tensions in communities and widespread anger at the police and local polititians. These do not seem to be there on anything like the same level. These riots seem to be using the shooting as an excuse to cause chaos and to go on the rob.
This is why I could never live in London. It is a very schizophrenic city. Areas of extreme poverty and high crime next to areas of extreme wealth. I just looked at a job in the city, £250,000 for an identical house to my own (worth £145,000). Ex social housing on a sink estate upwards of £180,000. A two bed flat, over £1000 a month in rent. Yet there is high gun and knife crime and areas of the city which are little more than gettos. Never mind the Olympics next year. London has far bigger problems to solve.
