That would imply that the vast majority of rioters are fascists and it is likely they aren’t. The people being convicted so far (and as the article says, they have tended to be charged with lower order offenses, it seems like those who were most heavily involved are coming down the pipe and will get harsher sentences) tend to be knuckleheads, opportunists, career criminals and people with nothing to loose who just want to watch the world burn.
It should be no surprise that in Liverpool riots took place in Walton, one of the most deprived areas of the country. A lot of the kids there have no future, so will take any excuse to smash things up (stupidly, including a community-run library).
