London Riots and " The destructors"

I saw a lot of pictures on the Internet, and I am very shocked that how they could do such violent things nowadays in London. I was also very shocked when the riots took place in downtown,Vancouver. However, this time the riots in London seemed much more serious. I looked for some information and I tried to find out the cause of this riot happened in London this time.There are several possible causes such as the social irresponsibility, the economic crisis or the lack of response of the police when confronted by the protest. As most of them are young people, and I think they don't know how to behave when they feel pressure; also, they don't empathize others properly. On the other hand, in " the destructors", it is understandable that those young children destroyed the house because they grew up right after the war, and maybe it was because of the way how they were raised up, and they became violent naturally. As the damage in London is very huge this time, I hope they can rebuilt those damaged things again soon, and I also hope they can live a peaceful life there.
