Whilst I think the response of the Spanish authorities were poor. I think it would be wrong to argue the present referendum gave a democratic legitimacy to Catalan independence. This was not a free and fair vote. (It matters little whose fault this was).
The best outcome is if this could be used to move to a proper referendum.
I agree, but only after those who have broken law in pushing such a referendum through get punished. It was clear they wanted the Spanish police to supress the referendum, it was clear the referendum would give them no democratic mandate and they declared they would announce independence within 48 hours of the results, if it was in their favor - regardless of the problems this would cause to their constituencies and the continent as a whole. This is not democracy any more than the Spanish police response is.
I think Madrid needs to rework their strategy on how to keep Spain together. It's not so much that Catalonia deserves a free and fair referendum as it is the only way it will keep the passions subdued for another generation. Granted this is but buying more time, the precendens it creates will ensure the state will disintegrate at a certain point in the future. But perhaps another generation or two is all it is needed, perhaps in 30-40 years or later when the vote goes in favor the EU integration will be so advanced that breaking Spain apart will be as disruptive as making two communies/municipalities out of one.
