There is a town near me that attracts a lot of far right protestors due to a major child sex abuse scandal. They are overwhelmingly from outside the area and just looking for an excuse for a scrap. The Police tend to kettle them up on an industrial estate for the duration.

It's not unreasonable to think that the sort of neo-nazi terrorism affecting America could easily happen here. There's certainly not a shortage of irrationally angry white men who blame minority groups for absolutely everything in this country.
