The far right itself can be difficult to pin down because it isn't exactly a coherent global movement or political party with a concrete set of ideas.
The far right are constantly threatening violence but people think, 'Oh they're just stupid lads, they're all talk...they'll never do it.'
As we move forwards and think collectively about how we address racism and combat white nationalism as a society, is the very idea of 'preventing' extremism a fool's errand? Should the authorities just be concentrating on catching and prosecuting those who attempt and commit crimes?
