Good post from Squander Two. Two related points from it:
I'm all for constraining democracy within awkward undemocratic boundaries, as, for instance, the USA's system does. Imagine how much better British governance could be if the Deputy Prime Minister were always the Leader of the Opposition and the Prime Minister were forced to work with him.)And, possibly more tongue-in-cheek:
Anyway, the whole point of the Northern Ireland Assembly is that the views of all Northern Ireland's political factions are represented, to encourage them to get involved in democratic politics rather than terrorism. So, by its very definition, the Assembly is supposed to contain at least one member who approves of this bombing. When every member of the Assembly condemns this attack, what that demonstrates is that they've set up the Assembly wrong.
