I find the whole immigration/race angle very interesting. Whenever something like that happens, there's a bunch liberal minded folks with good intentions who start talking about institutionalized racism, police brutality and targeting the minorities, economic hardship that's common to the areas these troublemakers come from, etc etc.
I wonder though what would happen to these scumbags if they tried doing these things back in the home countries where their families came from to the UK. I can guarantee you they used to live in a shithole with no government support system to speak of and the law enforcement they had to deal with makes the worst British policeman look like a Santa Clause by comparison.
