It's not a court case but the analogy is strong -- the Yes campaign has to make its case far more than the No campaign does. That's always true whenever anyone proposes change of one form or another. Voting, or supporting, the Yes campaign because of bad "no" campaigning, meanwhile, overlooks the occasionally seriously nasty tactics from "yes" supporters. The separation between the two countries is far, far less significant than some people are making out, I think. There's just far less of a case for independence culturally, politically and socially than in, for example, the Eastern European countries AOG mentions. There was active subjugation under the Soviet/ puppet regimes.
Tensions are clearly simmering. Tomorrow and particularly on Friday they will most likely come to the boil. Especially if it's a "no" vote.
