Well, it's an interesting point, but the reaction here is more often an assumption that the person found with explosives is guilty, no matter what colour they are, maybe that's a rollover effect from the IRA here.
The annoying part is that Terrorism is Terrorism, it shouldn't matter who the person is affiliated with, either we treat it as such or we don't.
I'm frankly amazed that the National Press isn't all over this, it's perfect front-page material in many ways, you'd get to put the words 'Terrorist', 'Bomb', 'Nazi' and 'BNP' in a single paragraph, they'd be drooling over the keyboard, I would have thought.
