I tried to think of a reason for the riots and all I came up with was that British, same as all western society, places great value on material goods and these people aren't being given the jobs to pursue those material goods legitimately.
But guess what, I'm poor and want a 30" TV and an iPad 2, so you know what I do? Work at Pizza Hut while I'm at University. I was born in a poor area too so there are no excuses there.
If I were in London, living on a high street, I'd be up all night with a camera making sure I took 100s of pictures of every rioting cunt out there. Arrest them, make them build a prison and put them in it. Cunts.
