Because the far-right have never indulged in violence, ever, and anyone who suggests the Norwegian authorities must start investigating Neo-Nazi groups must be part of a Stalinist plot to takeover the BBC and steal our precious bodily fluids.

The fear isn't a clampdown on the extreme-right
per se, it's the fact that an astonishing number of people have quite a "broad" definition of what counts as "far-right" or "Neo-Nazi". Some people would even put UKIP into this category. Anyone for whom he has expressed support is tainted (it's true that this happens with all terrorist attacks, but it's usually not as dangerous because, as a rule, groups like al-Qaeda tend not to voice support for legitimate politicians and parties).
