Birmingham riots?

for those who live in England, we all have heard about the huge riots in London? well apparently they have spread to Birmingham :/

well to be honest it's probably just chavs, but apparently big stores have been attacked.

Why??

Really have they got anything better to do, because attacking police officers and setting buildings on fire it's so stupid. What do they think they are going to achieve really?

Can any one who knows anything tell me? because it sounds so violent and my favourite shops have apparently been destroyed and there are crazy rumours flying around.

stupid rioting chavs :(
